Voltage and current in an ac circuit are given by \[V=5\sin \,\left( 100\pi t-\frac{\pi }{6} \right)\] and \[I=4\sin \,\left( 100\pi t+\frac{\pi }{6} \right)\] [Kerala PET 2001]

• A.            Voltage leads the current by \[{{30}^{o}}\]
• B.            Current leads the voltage by \[{{30}^{o}}\]
• C.            Current leads the voltage by \[{{60}^{o}}\]
• D.            Voltage leads the current by \[{{60}^{o}}\]
