Voltage and current in an ac circuit are given by
`V=5 sin (100 pi t-pi/6)` and `I=4 sin (100 pi t+pi/6)`

Options

A. voltage leands the current by `30^(@)`
B. current leads the voltage by `30^(@)`
C. current leads the voltage by `60^(@)`
D. voltage leads the current by `60^(@)`

Answer

C

Explanation

Phase difference, `Deltaphi=phi_(2)-phi_(1)=pi//6(-pi//6)=pi//3` or `60^(@)`\
