Answers to Questions
Chapter 1
1. A transformer is an electromagnetic device that transfers energy from one circuit to another through mutual inductance.
2. AC. It is more efficient
3. The primary windings of a transformer are connected to the source voltage, and the secondary windings are connected to the loads.
4. “H” terminals indicate the high-voltage windings, and the “X” terminals indicate the low-voltage windings.
5. Transformers are rated in kVA. They may have to deliver current to loads which do not consume power (watts) such as inductive and capacitive loads.
6. Step-up. “X”.
7. No. The output kVA must equal the input kVA.
8. Maximum power will be transferred when the impedance of the load is equal to the impedance of ...
