# Resonance and its applications

### Explanation of question 13

In a resonant circuit, the supply current

1. is in anti-phase to the supply voltage
2. is in phase with the supply voltage
3. lags the supply voltage by 90°
4. leads the supply voltage by 90°

The answer is :- 2 A circuit at resonance behaves as a pure resistor, therefore the supply voltage and current are in phase.
