The inductance will be 1.5H

Explanation:

When current passes through an inductive coil magnetic field is produced in the surrounded area of coil.

Consider the DC equivalent of the circuit in figure.

 

Voltage applied = V = 100V

Resistance of coil = RL = 15 ohm

Resistance = R1 = 10 ohm

Energy stored = W = 12J

According to ohm’s law

V = IRt

I = 100/25 = 4A

Now,

W = ½ LI^2

L = (2) (12)/4^2

L = 1.5 H
