# Compound alternating current circuits

### Explanation of question 4

At a given frequency, a capacitor has a reactance of 24. When connected in series with a 10 resistor to the same frequency supply, the circuit will have an impedance of

1. 14
2. 22
3. 26
4. 34

The answer is :- 3

XC = 24 R = 10

Thus Z = 26
