Question

The energy stored in the inductor is?

(a) Li²/4

(b) Li²/2

(c) Li²

(d) Li²/8

This question was posed to me in an online quiz.

I'm obligated to ask this question of Circuit Elements and Kirchhoff’s Laws in portion Circuit Elements and Kirchhoff’s Laws of Network Theory

Answer 1

Right answer is (b) Li²/2

For explanation I would say: The energy stored in the inductor the area under the power of the inductor and is given by W = ʃpdt = ʃLidi = Li²/2.
