8 Questions

1. Efficiency is always the ratio of output to input. It is the ratio of true (output power) to apparent (input power).

2. (+) = Positive and (-) = Negative. Also see Transformer Polarity.

3. The winding that is connected to the load. It does not necessarily have to be the low voltage winding.

4. The result of the energy wasted in reversing the magnetization of the core every time the current reverses and magnetizes the core in a different direction

5. The rating of a transformer in kilovolt- amps.

6. The effects of inductance are mutual between the primary and secondary. The current in the primary induces a voltage in the secondary.

7. The primary winding is the winding that is connected to the source voltage. It does not necessarily have to be the high voltage winding.

8. Polarity where the HI marking is opposite the X2 marking and the H2 marking is opposite the X1 marking.
