Inductance

Question

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 2 A in 1 millisecond. The value of self inductance is

Moderate

A

Zero
B

5 H
C

5000 H
D

5 mH

Solution

$L = \frac{e}{di / dt} = \frac{5}{(3 - 2) / 10^{- 3}} = \frac{5}{1} \times 10^{- 3} = 5 milli henry$
