If 0.1 J of energy is stored for the flow of the current of 0.2 A in an inductor, then its inductance value (in H ) is

Correct answer

5

Step-by-step solution

The energy stored in an inductor is given by the formula U = 1 2 L i 2 Given, U = 0.1 J , i = 0.2 A 0.1 = 1 2 L × 0.2 2 ⇒ L = 2 × 0.1 0.2 2 = 0.2 0.2 × 0.2 = 10 2 = 5 H
