# Simple alternating current circuits

### Explanation of question 1

A resistor takes a current of 0.1A from a 24V AC supply. The value of the resistor and the power dissipated will be respectively

1. 2.4, 2.4W
2. 2.4 3.4W
3. 240 2.4W
4. 240, 3.4W

The answer is :- 3

R=V/I = 24/0.1 = 240

P=V x I = 24 x 0.1 = 2.4W
