Question

An E.M.F of 5 V is produced in an inductor, when the current changes at a steady rate from 3 A to 2 A in 1 millisecond. The value of self-inductance is, zero, 5 H, 5000 H, 5 m H

MARKS App · Accepted Answer

Magnitude of self inductance is L = e d i d t L = 5 ( 3 - 2 ) 1 0 - 3 = 5 × 1 0 - 3 L = 5 m H
