QUESTION 1 LECTURER: NATHANIEL A NELSONg the increasing desires on energy efficiency, environmental protection and energy cost, the development of electronics vehicles technology has been the other trend. Based on the air pollution in the world, the fossil-fueled cars have been targeted as the prime source of emission that continues to create air pollution leading to global warming crisis. It was found out that the new discoveries are of slow pace; therefore the need for an alternative is crucial. Discuss the way forward as in what will help to achieve the energy efficiency, energy cost and the environmental protection we desire. Your solution must not be less than two pages. Ensure to touch on all relevant areas to convince scholars. [10 Points) b. In our bid to regulate power flow of 110V, 60Hz input to an output (load) circuit made up of resistor of 42 and reactance of an inductor of 612, the University nominated you to give a presentation on how to achieve the said objective if a single phase voltage controller and thyristor are involved. Your presentation should determine all relevant values needed to attain the objectives.[10 points). c. I If the available parameters are appreciated by 50% with the exception of the 110v and the 60Hz, determine same as demanded in (b) above. [5 Points] QUESTION 2. a.i Discuss in detail the system or the technology which was found to be widely used in many fields, like factory automation systems, research science and technology contest and many more [6 Points) ii. Expand on the system that ruggedizes compuer which is employed for automation processes and that of the one containing multiple autonomous controllers for the same purposes stated above. [4 Points) b.i. After a thorough investigation it was detected that the automation system failed to maintain a zero error between process varriable and set point to the device. [5 Points] ii Discuss the organ of the automation system that noticed the low level signal. Also state clearly the duty of that part. [3 Points] iii. Detail us in the various programming languages available in automation systems. [2 Points] ci. Discuss 2-wire, 3-wire and 4-wire transmitters in automation. [3 Points) 1. What are some of the issues encounted by the adoption of automation. [2 Points] QUESTION 3. a Discuss the situation that led to the development of depletion layer region in a half conductor and half insulator property. Share light on what needs to be done to improve the potential barrier to enable us achieve our objective. Provide all relevant structures and diagrams to buttress your discussion, your solution should not be less than two pages. [10 Marks] bi. Discuss the relevance of our emerging technology that has made life bearer able in this age. Deliberate on all key parameters and components that will be needed to accomplish the set objective. [10 Marks] c. In automation environment Electronic Controller can be described as what and which area of application can it be found? (5 Points) QUESTION 4. . . With the aid of a simple waveform diagrams of both single and three phase power suply, distinguish between the two stating the conductors which are out of phase and space 120 apart from each other ii. Under the basis of comparison, six areas of the single and three phase power supply can be distinguished as what? [10 Points) i. Draw the two types of three phase power supply system with a load and indicate on the diagram how the VL, IL and Vph are measured. ..Give four areas of operations of the two types of three phase power supply. [10 Points) In a three phase power system 1.5kw of power and 230v was given. Determine the power factor (pf) which takes account of the difference between the real power and the apparent power.
