Voltage and current in an ac circuit are given by
P
\( V=5 \sin \left(100 \pi t-\frac{\pi}{6}\right) \) and \( I=4 \sin \left(100 \pi t+\frac{\pi}{6}\right) \)
(1) Voltage leads the current by \( 30^{\circ} \)
(2) Current leads the voltage by \( 30^{\circ} \)
(3) Current leads the voltage by \( 60^{\circ} \)
(4) Voltage leads the current by \( 60^{\circ} \)
