A. You need to know more details about the following two differences. AC motors are driven by AC electricity. A DC motor requires DC electricity to run. AC motor is low cost and easy to run. But running a DC motor costs more and requires an inverter. AC motors require DOL, star-delta, and forward reverse starters which are readily available. Driving DC motors requires frequency converters and power diodes, which are expensive. I hope you understand. Good (1.5 Marks)
AC electricity is generated by an AC motor.
DC electricity is generated by a DC motor.
B. You have presented the workings of the electrical switchgear in your house beautifully and introduced us to some very important switches. Knowing the use and working of switchgear is important for all of us. Hopefully, you know about each switchgear. Very Good (2 Marks)
C. You have used the power factor formula to determine the motor specification. Advance used an electrical formula. Knowing how to use formulas is essential for an electrician. But the power factor has a standard value in every country. 0.8 to 1.00 is considered in our country.
The current output of your 5HP motor is correct. As an electrician, figuring out the current and power of motors is an important task. You have succeeded. Very Good(3 Marks)
D. The power circuit diagram of your star delta starter is nice. Electrical accidents are reduced if the electrical circuit design is accurate. It is a very nice circuit drawing and mentions the functions. Hopefully, you will practice electrical work more and learn more from the next lessons. Very Good (3 Marks).
