The average e.m.f. induced in a coil in which the current changes from `2` amperes to `4` amperes in `0.05` seconds is `8` volts. What is the self-inductance of the coil?

A

`5 H`

B

`10H`

C

`11H`

D

`12H`

Text Solution

Verified by Experts

The correct Answer is:
C
`|e|=L(di)/(dt)implies220=Lxx(100)/(0.5) =L=11H`
