An e.m.f. of `5 "volt"` is produced by a self-inductance, when the current changes at a steady rate from `3 A` to `2A` `1`millisecond. The value of self-inductance is

A

Zero

B

5 H

C

5000 H

D

5 mH

Text Solution

Verified by Experts

The correct Answer is:
D
`|e|=L(di)/(dt)rArrL=5/(di//dt)=5/(((3-2))/(1xx10^(-3)))=5mH`.
