The variation of the instantaneous current `(I)` and the instantaneous e.m.f `(E)` in a circuit is as shown in figure. Which of the following statement is correct?

A

The voltage lags behind the current by `pi / 2`

B

The voltage leads the current by `pi // 2`

C

The voltage and the current are in phase

D

The voltage leads the current by `pi`

Verified by Experts

The correct Answer is:

B

`E = E_(0) sin omega t`
`I = - I_(0) cos omega t `
At t = 0 , E = 0 and `I = - I_(0)`
Voltage leads the current by `(pi)/(2)`
