The stored energy in an inductor:
A) depends, in sign, upon the direction of the current
B) depends on the rate of change of current
C) is proportional to the square of the inductance
D) has units J/H
E) is none of the above

Question

Quizplus · Accepted Answer

The stored energy in an inductor is actually proportional to the square of the current flowing through it and the inductance (1/2 LI^2), not dependent on the direction of the current, not directly dependent on the rate of change of current, and its units are joules (J), not J/H.
