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

`5H`

C

`5000 H`

D

`5 mH`

Text Solution

Verified by Experts

The correct Answer is:
D

`L=(e)/(di//dt)=(5)/((3-2)//10^(-3))=(5)/(1)xx10^(-3)=5` milli henry
