1. what is a balanced 3system? 2.) what are advantages of 3? 3.) explain why it is true that without the transformer, it would simply not be possible to use electric power in many of the ways it is used today. 4.) explain how a transformer is able to change one ac voltage level to another voltage level and why the actual power supplied is not affected. 5.) what is a practical transformer? how does it differ from an ideal transformer? 6.) what is the purpose of power factor compensation? 7.) why is the name "synchronous" machine used? 8.) how does an induction motor differ from a synchronous machine? 9.) draw the single phase equivalent circuit of a 3induction motor. now draw the thevenin equivalent. 10.) list applications of the 3synchronous generator and the 3 induction motor.
