# Simple alternating current circuits

### Explanation of question 8

Two 5mH inductors of negligible resistance are connected in series across a 1kHz supply. The total reactance of the circuit will be approximately

1. 126
2. 63
3. 31
4. 16

The answer is :- 2 Total inductance = 5 + 5 = 10mH. XL = 2 x PI x F x L = 2 x 3.14 x 1000 x 0.01 = approximately 63
