When the current in a coil changeg from `8` amperes to `2` amperes in `3xx10^(-2)` seconds, the e.m.f. induced in the coil is `2` volt. The self-inductance of the coil (in millihenry) is

A

`5H`

B

`3H`

C

`4H`

D

`2H`

Text Solution

Verified by Experts

The correct Answer is:
C
`|e|=L(di)/(dt)implies30=Lxx((6-0))/(0.3)=L=1.5H`
