Inductance

Question

Two circuits have coefficient of mutual induction of 0.09 henry. Average e.m.f. induced in the secondary by a change of current from 0 to 20 amperes in 0.006 second in the primary will be

Moderate

A

120 V
B

80 V
C

200 V
D

300 V

Solution

$| e | = M \frac{di}{dt} = 0.09 \times \frac{20}{0.006} = 300 V$
