# Simple alternating current circuits

### Explanation of question 6

A coil of negligible resistance has an inductance of 0.5H. It is connected across a 6V, 50Hz supply. The power dissipated in the coil will be

1. 15.7W
2. 2.62W
3. 38mW
4. zero

The answer is :- 4 No power is dissipated in a pure inductor.
