Using An Electric Motor Fan Engineering Essay

Using An Electric Motor Fan Engineering Essay The resistance value for experiment 1.1, 1.2 and 1.3 calculated and was 93.23 , 101.01 and 100.90 respectively. The effect of voltage increase on temperature was recoded and how power is lost as heart was understood. How electrical current generate magnetic field was observed by using compasses and explained. An experiment was also carried out and explained in to how electromagnetic field is used to control electrical circuits involving more than one circuit in a relay. The change of electrical energy to mechanical was also investigated by using an electric motor-fan. Background Despite the famous experiment Benjamin Franklin, he did not invented electricity. Electricity exists naturally. It has always been around. A good example of electric flow that occurs naturally is lightening. Lightening is a flow of electrons between the ground and clouds. When clouds rub against each other or other objects they become charged. When the potential difference between the clouds and ground reaches a certain level a flow of electrons balances the charge, this exhibits a flash of light or lightening1. Electrical systems and components can be classified into several capabilities and used for many different applications. Electrical components and systems can be used to heat, power, sense, drive, detect, indicate, to transmit and receive data2. Electrical equipment such as light bulbs, batteries and electric generators are not needed for electric city to exist, although designed to use and harness electric city. If potential difference or voltage is maintained across a conductor an electric flow occurs, Figure1. The currents magnitude depends on the voltage. The Ohms law states that the current through a conductor between the two points is directly proportional to the potential difference across the two points. Therefore if the potential difference applied across a conductor is changed the current will also change. If a device follows the Ohms law the graph voltage vs current should have a straight line3. By rearranging the equation 1, voltage can be calculated; in addition the resistance of material can simply calculated by dividing the voltage to the current see equation 1. V R=V/I Figure1. An electric potential across a conductor3 Equation 13 The two types of circuits are series and parallel. Total resistance in series circuit can be determined by adding the individual resistors resistance. To find the resistance of two or more resistors connected in parallel, the sum of the inverse individual resistance is used2, Equation2. Equation 24 In electrical circuit some power is lost as heat. Resistance and heat loss is directly proportional for a given volts. Therefore if the volt is increased the resistance will increase, this will then result in a great deal of heat being lost3. When there is a need to control more than one circuit, a relay is used. Relay is a switch operated by electric. The mechanical movement of a relay is often controlled by magnetic force. The flow of current through the relay coil generates a magnetic field and changes the switch by attracting a lever. Relay aid one circuit to switch to another circuit and operate completely separate from the initial circuit5. Relay coil NO COM NC Figure 2. Relay contact5 Key COM  = Common, always connect to this, it is the moving part of the switch. NC  = Normally Closed, COM is connected to this when the relay coil is  off NO  = Normally Open, COM is connected to this when the relay coil is  on If an electrical current flows through a wire, a magnetic field is created due to the moving charges. Figure 3 demonstrates the magnetic fields in a straight conductor. The magnetic field for a straight conductor circles around the conductor. As illustrated from figure 4, a wire is coiled up to make a solenoid. The flow of the current determines the magnetic field direction. Each loop experiences its own magnetic field and the total magnetic field is the sum of individual loop. In addition the magnitude of the total magnetic field of a solenoid is directly proportional to the number of coils a coiled wire has7. Magnetic Field Around a Wire VRML Model Figure 3. Magnetic fields in Straight conductor7 Magnetic Field of a Solenoid VRML Model Figure 4. Magnetic fields in solenoid7 Electric motor is one of the very useful appliances use electric power to turn in to mechanical energy. To understand how an electric motor work simply imagine a nail wrapped with a wire and connected to a battery Figure 5. If the battery is connected to the wire, the nail would eventually become a magnet and have a south and North Pole. If the nail is suspended in the middle of a horseshoe magnet as in figure 5, the north end of the nail would be repelled away from the horseshoes north end and attract to the south end of the horseshoe. By doing this the nail would half turn and stop at the original place. To maintain a full turn the electromagnetic field of the nail should be flipped at a very precise moment. This is done simply by changing the direction of the electrons flow6. http://static.ddmcdn.com/gif/motor-nail-in-horseshoe.gif Figure 5. Electro magnet in a horseshoe magnet6 Experimental Experiment 1.1: Electrical circuit As illustrated in figure 6, a series circuit was set up and one resistor was used across the circuit. Multi-meters were used to record the voltage across the resistor and current. Five different voltages in the range of 2 to 12 volts were applied and the current was recorded for each for each volts. Power R1 V A Figure 6. Series one resistor circuit2 Experiment 1.2 Similar procedure was used to record the voltage and current for the second experiment, this time though two resistors were used. V Power R1 R2 A Figure 7. Series two resistor circuit2 Experiment 1.3 In the third experiment two resistors was set up in a parallel circuit. Similar method to experiment one and two was used to record the voltage and current. Power A R1 R2 V Figure 8. Two resistors in parallel2 Experiment 2: Temperature vs. voltage In the fourth experiment investigates the relationship between voltage and temperature across a resistor. Similar circuit to experiment was, but this time one of the multi-meter was used set to record temperature. A thermocouple as shown in figure 9 was used to detect the temperature change and this was fed to the multi-meter8. http://images.picotech.com/se001-thermocouple.jpg Figure 9. Thermocouple8 Experiment 3: Relay Figure 10 shows the mechanism of the relay. A switch was used to control the relay by switching between the two circuits. Figure 10. Diagram for connection of experiment with relay and LEDs2 Experiment 4: Electric motor Fan An electric motor was used and given a power of 12 volt. Electric current was controlled by a switch and the fan rotated as due to the magnetic field generated by the electric. Experiment 5: Magnetism In these experiment two methods was used to test electro magnetism of electric of the flow of current. A wire used to flow electricity and magnetic compass was placed around the wire. In the second method a coiled wire was used and compasses was placed in the inside and outside of the coiled.

Figure 12. Voltage vs Temperature Experiment 3: Relay When the switch was turned on LED one turned on and when the switch turned of LED one light gone out and LED two turned on. Experiment 4: Electric motor Fan The electric motor-fun started to spin only when the electric current started to flow. This was controlled by a switch for convenience. Experiment 5: Magnetism The results of electro magnetism were observed in experiment 5. When a single wire was used the compass needles aligned themselves towards the direction of the current flow. In the coiled wire when the compass was placed inside the coiled wire the compass pointed towards the direction of the electric flow. When the compasses was placed outside the solenoid the compasses experiences a great deal of deflection in comparison with the single wired cable. Discussion Experiment 1.1 1.3 circuit Figure 11 demonstrates an increase in voltage resulted on an increase in current. For the circuits with two resistors in parallel and series the graph was showing a positive correlation between the voltage increase and current increase. For the series circuit with one resister there was an anomaly when the voltage was set to 6 volts. The increase in current at 6 volts was too high, and this resulted on the graph being nonlinear. To make assumptions that the circuit obeys Ohmic law the graph should be linear. Possible source of errors; Human error (error when recording figures) Faulty multi-meter being used Faulty resistors or Faulty power supply reading Experiment 2: Temperature vs voltage As illustrated in figure 12, as the voltage increase the temperature across the resistor also increased. The temperature was directly proportional to the voltage increase. Temperature increase was steady for every additional volts applied for up to 6 volts. Temperature increase was doubled then doubled when 8 volts was applied. Some of the factors that can affect the amount of heat loss in a circuit are; Type of material used for wiring or resistor (some material are good conductors and some are very good insulator) Wire diameter (the smaller the diameter the harder for the electrons to move through) Length of wiring Temperature of the material/conductor (lower temperature result in lower resistance and indeed lower heat loss)3 The sharp increase in temperature was due to possible errors; Faulty thermocouple Leaving a particular voltage slightly longer than the another Breathing near the thermocouple (increase in the overall temperature) Experiment 3 Relay Figure 10 demonstrates the relay experiment. Since the relay mechanism was very small to be observed by the naked eyes LED was used to indicate if the electrical flow was switching in between the two circuits every time the switch was hit. TQ team7 States that the total magnetic field in a loop is the sum of its individual loop. Since moving charged particles generate electromagnetic field many charged particles generate a higher magnetic field. Therefore higher resistance in the wire coiling of a relay could cause the relay not being able to attracting a lever. Higher resistance in relays could be caused by rusting or using materials with low conductivity. Experiment 4 Electric motor-fan The power used in the Electric motor-fan was DC current. The current in DC always goes through one direction. The electric-fan began rotating when the current starts to flow. The current flow was switched over, as the polarity of the volt switched over, it was expected the motor start running the opposite direction instead the motor was stopped. The fan was possibly fitted with a device that only allows a one direction flow of current9. A diode was one of the possibilities that the electric motor-fan was fitted by. A diode is a two terminal device, with features of some systematic transfer of electric city character. A diode have a zero resistance to electric flow in one direction and high resistance (100%) resistance in the other direction, therefore electrical current flow only in one direction. Experiment 5 Magnetism As demonstrated from figure 3 and 4 electric current produces magnetic field. The compass used for the single wire deflected and seen aligning itself with the direction of the electric current. By observing the deflection of the compass needle, the North and South Pole of the magnetic field was deducted10. Conclusion The goal of the experiment was to understand the role of electricity in modern technology. Resistance in series and parallel circuits were tried, electromagnetism and its applications explained. The experiments deduction narrated below; With the exception of one anomaly result the circuits in experiment one obeys Ohmic law, therefore a linear graphs. In series circuit the resistance value doubled when another resistor was added. As it can be observed from table 2 resistance values for the parallel with two resistors was almost half the value for the series circuit with one resistor. Parallel circuit resistance was very small when compared with the resistance value in the series circuit with the same number of resistors. The value for the resistors calculated as 93.23 , 101.01 and 100.90 respectively. In experiment two, power dissipation promotes temperature increase . Relay experiment demonstrates the control of more than one circuit by using magnetic field of electric current. Charged moving particles produce a magnetic field Electric motor-fan converts electrical power in to mechanical by the help on a magnet inside the motor. Compasses used to observe the direction of an electric current. The grater the loop the grater the deflection the compass experience. Figure 3 and 4 demonstrates the magnetic field in a single wire and solenoid.

Ibus Essay

The multiple choice questions will be conceptual, not factual. In other words, I will not be asking country specific questions and details; but will ask you to identify concepts, pick the correct characteristics/dimensions of concepts from alternatives and apply concepts to real life situations. All chapters are almost equally represented in this section. 3 descriptive/conceptual essay questions (8 to 12 points, 30 points total): This section is again conceptual. I might ask you to describe a theory or concept, identify and classify certain dimensions of cultures, or fill a table (that I provided) with missing information. If you cannot remember the terminology, you can define things in your own words (and get partial credit to the least). All chapters are fair game for this section. 1 integrative/comprehensive essay question (15 points): For this question, I will ask you to take a position on a course related issue. Obviously, there is no single right answer. You will be evaluated based on the quality and depth of your argument rather than the position you take. While you are not required to know country/marketplace specific information, don’t hesitate to use examples to support your position. To answer this question, you might need to information from more than one chapter. The exam is closed book, but you can bring a paper dictionary (non electronic). I will not be using an IBM sheet for the multiple-choice section; this means that you can use either a pen or pencil to answer the questions. You won’t be graded for grammar, spelling or your essay skills, so don’t panic about it. There is no optional question at this exam.

Customer service contributes to customer satisfaction Essay

Introduction: In this Assignment I want to describe how consistent and reliable customer service contributes to customer satisfaction, explain why presentation, interpersonal and communication skills are important to customer service. And I will also anticipate and meet the needs of at least three different customers in a range of situations. Task 1 In this task I should describe how consistent and reliable customer service contributes to customer satisfaction. The national consumer council believes that smart businesses should ensure that the same member of staff deals with an individual customer from the beginning to the end what means if you welcome a customer you should try to deal with the customer and help the customer till the customer wants to go or dos not need your help anymore or till he buy something. Whilst this is the ideal, it isn’t always possible. Therefore, most organisations provide special training to staff to ensure that each person has the same approach with external customer. This is likely to focus on the following aspects of the job. * Scope of job role – You should know what you can do and what you can not do as part of your job and the type of issues you must refer to a supervisor. This should not stop you using your initiative to resolve a straightforward problem quickly, for example if you have nothing to do you should use your own initiative to look for something to do till a customer comes or if a customer has a problem by not finding what he wants to buy you can ask them if they need your help and if you can help them you should help by explaining where they can get it from and you should take care that you do not overstep the limits of your job role by making arrangement or promises that is outside your authority. * Type and quality of product or service – That means you should know the range of goods or services that are available, if you are selling consumable items, such as chocolates. Anyone who sells expensive items or complex services should also be able to give good advice on the best buys or most reliable suppliers, based on their own knowledge, feedback from other costumers and press reports. * Accessibility/Availability – There is nothing more irritating for customers that to want something and then find they are not available. This can relate to a product they have seen advertised but which has now sold out for example if you have an appointment with someone who cannot see you for some time or a room in a hotel which is fully booked. In this situation your job is to sympathise with the customer’s disappointment; try to help them if you can and pass on the information to your employer. This is important. If you have received many enquiries for the same thing in a day and disappointed most people, the stock levels for this product should be reviewed. * Staff attitude and behaviour – The importance of all staff having a consistently positive attitude and behaving courteously and professionally to customers cannot be underestimated. This means if your staffs have good attitude and behaviour the customers will feel comfortable and free to talk to the staff and it also makes customers feel valued and respected. * Timing – Approaching people at the wrong time, or if they are stressed, upset or busy can get a bad response. If you do this by accident, simply apologise and say you will contact them later. Being aware of your timing also means not keeping people waiting unduly; arranging appointments, phone calls and deliveries at your customers convenience, not yours; and never failing to call people back exactly as you promised. By this way you appear reliable to the customers. * Meeting specific customer needs – The skills of meeting customer needs involves identifying these by talking to the customer, and then matching them to the range of goods and services that you can offer. Most customers are pleased with this aspect of customer service because it gives them a sense of importance. Task 2 In this task I should explain why presentation, interpersonal and communication skills are important to customer service. Presentation skills – These skills relate to me as a person. What do other people see as I approach? Do I attract them or alarm them? This has nothing to do with good looks but everything to do with a welcoming smile, appropriate clothes and a smart appearance. Presentation skills include: * Body language; Body language is one of the presentations skills. Body language is a term of communication using body movements. One of the basic body language signal is when a person is crossing his arms across the chest this can mean that the person is putting up a barrier between himself and others but it can also mean that a the person is expressing opposition this is specially so, if the person is leaning away from the speaker. But crossing his arms across the chest can also mean that the person is deeply thinking about something. You can show someone that you are interested in what he is telling you if you keep eye contact. * Another presentations skill is also the dress code which means if you work in an office you have to wear a dress or if you are working somewhere else where they have their own uniform you must wear their uniform and it has to be clean. Many people will consider it impolite if your dress is too far above the dress code. Too far means if you are working for example in ASDA and you are wearing a coat to work, many customers will not know that you are one of the staffs. But if you are working in an environment where they don’t have to wear any uniform, then you must have a good sense to dress properly. * Facial expression is also a presentation skill; facial expression is a result from one or more motions of the muscles of the face. This movement convey the emotional state of the individual to observers. Facial expressions are a form of nonverbal communication. Expressions are closely tied to emotion. It can be nearly impossible to avoid expressions for certain emotions because if you see someone that you think he or she is highly unattractive you might show a brief expression of disgust before you will be able to reassume a neutral expression and if you don’t have this skill it may be hard for you to work in an environment with different customers or other staff members. Interpersonal skills are how people relate to one another, in other words it means how you behave when you are dealing with other people. Having positive interpersonal skills increase the productivity in a business. Interpersonal skills include: * First impression; your interpersonal skills are on show from the moment you greet a customer to the time you say goodbye and if your first impression to a customer is good the customer might come again. * Behaviour – This is what you do and why you do it in other words it is the actions or reactions from you, for example if you are a positive person, you will normally behave in a cheerful and friendly way to other peoples. * Attitude – Your attitude is the way you think. For example if you are depressed you will be negative, if you are fed up then you will be bored and if you are happy you will be friendly to other people. Communication skills – communication is a process whereby information is imparted by a sender to a receiver in other words you need to speak to you customer as well and how you do this is important. If you are communicating with a customer you must look after your * Your speech – this means that you should speak loud and clearly because if you are speaking too quietly or miss the endings of words, then the customer might have problems to understand you. * Your language – this means that you should use appropriate language for your customer because it is not appropriate to use slangs and jargons since the customer will not understand what you are talking about. * The pitch of your voice – this means that you should take care of how you sound. For example if you have to talk to a group of people you should raise your head and speak more loudly and clearly but without shouting. And you should know how to pitch your voice to hold the interests of your customer because if you sound monotone the customer will soon lose the interest. Task 3 In this task I should anticipate and meet the needs of at least three different customers in a range of situations. * Accessibility for disable peoples for example those with wheelchairs. The business makes their stores accessible for wheelchair user by having big signs that are clear and easy to read, a ramp as an alternative to steps, the doors should also be wide and easy to open and the widths are allowing wheelchairs and the height of counter areas and shelves also allows wheelchairs. The business should also have toilets that meet the needs of wheelchair users. And the staff should also take time to help peoples in wheelchairs if they need help. * Health and safety – The business makes their store healthy and safe by making sure that all selling environments are assassed for risk so that any hazards are minimised, it means, the business must keep the workplace clean, they must make sure that their floors, steps, stairs, passages and gangways are properly maintained and it is kept from any obstruction and any substance likely to cause a person to slip and fall. If you, as a staff member, see something that can affect the health and safety in the business then you should do something about it before something happened, for example if you see something on the floor that can make someone fall then you should take the thing away from the floor or if the floor is wet you should put a sign there that the floor is wet so that no one can fall. * Email – The business makes sure that they have a email account so that they can send emails to customers and others. If you send a email you should make sure that you chose the right message style and layout and that you follow the recommended business format. And the email should also be written in a courteous and tactful way and also the wording should be appropriate for the situation. But it will be useful if for example you want to send an email to a customer you should mark the email as high priority if it will be important for the customer. And for you as a staff member you should have the skills to send an email which means that you should be a able to apply the appropriate customer service an to make sure that you chose a good tone and degree of formality depending upon the person and your reason for writing and it is important that the business mails should comply with organisational rules and recognised standards.

INTRODUCTION There have been several studies carried out regarding the effect of socio-economic status of students on their academic achievement. Some of these studies have conflicting results as to the relationship between students socio-economic status and their performance academically. Keeves and Saha (1992) opined that in most countries of the world, educational achievements are related to the social background of the students. This includes the gender of the students, the socio economic status of the family (and hence the student) and the ethnicity and language characteristics of the student. Studies carried out by Mok and Flynn (2008) to examine the achievement of students in catholic schools in New South Wales showed that parents level of education made a significant contribution to achievement. High Socio-Economic Status (SES) schools also scored better in the Higher School Certificate than medium or low SES schools (Mok and Flynn, 2008). In a meta analysis including approximately 200 studies by White (1982), a high correlation between SES and achievement was found (r = 0. 875), while Keeves and Saha (1992) demonstrated that SES indirectly influences student achievement while the direct effects on student achievement are associated with other variables. Beaton et al. (1996) reported that the more educational resources in the home the higher the student achievement than those who reported little access to such resources. Strong positive relationships were found between mathematics achievement and having study aids in the home. It was reported that in most countries where the Third International Mathematics and Science Study (TIMMS) were carried out, the more books the student reported in the home, the higher their mathematics achievement. Backman suggested that positive parental attitude towards their children such as high interest in their children’s academic efforts; provision of household equipment like television, computers, books, educative video, radio, good school, closeness and intimacy with children can bring about good academic performance. Fraser (1994) also looked at the effects of home environment on 408 Aberdeen children’s academic achievement and found out that two variables with the highest correlation with educational attainment are parental encouragement and parental education. In a home where parents are fairly or highly educated, there is the tendency that they would aspire to see their children better than they are educationally. This inspiration will force them to motivate their children by providing for their basic needs in education hence their performance in their academic work in school will improve.
