When current flowing in a coil changes from 3A to 2A in one millisecond, 5 volt emf is induced in it. The self-inductance of the coil will be-

A

Zero

B

5kH

C

5H

D

5 mH

Text Solution

Verified by Experts

The correct Answer is:

D

`_|_ = - V/((Delta i)/(Delta t)) = + 5/(10^3) = +5 xx 10^(-3) H = 5 mH`
