# Compound alternating current circuits

### Explanation of question 11

A capacitor and resistor are connected in parallel across an AC supply. Each component takes a current of 7A. The total current will be approximately

1. zero
2. 7A
3. 10A
4. 14A

The answer is :- 3 The two currents cannot be added together directly, but must be added vectorially thus

I2 = I12 + I22 = 49 + 49 = 98

I = 10A approximately
