Calculate the current in an Inductor if the energy stored is 240J and the Inductance is 24H.​
SCORPION-xisa [38]

Answer:

Current, I = 4.47 Amperes.

Step-by-step explanation:

Given the following data;

Inductance = 24H

Energy stored, Eind = 240J

To find the current;

The energy stored in an inductor is given by the formula;

Eind = ½LI²

240 = ½*24*I²

Cross-multiplying, we have;

480 = 24I²

I² = 480/24

I² = 20

Taking the square root of both sides, we have;

Current, I = 4.47 Amp
