# Voltage and current in an AC circuit are given by $$V = 10\sin \left (50\pi t - \dfrac {\pi}{6}\right )$$ and $$i = 2\sin \left (50 \pi t + \dfrac {\pi}{4}\right )$$.

**A**

Voltage lags the current by $$45^{\circ}$$

**B**

Current leads the voltage by $$30^{\circ}$$

**C**

Voltage leads the current by $$45^{\circ}$$

**D**

Current leads the voltage by $$75^{\circ}$$

#### Correct option is C. Current leads the voltage by $$75^{\circ}$$
