In the case of an inductor

A

voltage lags the current by `pi `/ 2

B

voltage leads the currrent by `pi `/ 2

C

voltage leads the current by ` pi` / 3

D

voltage leads the current by `pi ` / 4

Text Solution

Verified by Experts

The correct Answer is:
B

In case of an inductor , e = L di/dt
`therefore` voltage leads the current by `pi`/2.
