Question

Quizplus · Accepted Answer

The energy stored in an inductor is given by the equation E = 1/2 * L * I^2, where E is the energy in joules, L is the inductance in henrys, and I is the current in amperes. In this problem, the inductance is 6.0 mH, which is equal to 6.0 * 10^-3 H, and the current is 5.0 A. Plugging these values into the equation, we get E = 1/2 * 6.0 * 10^-3 H * (5.0 A)^2 = 7.5 * 10^-2 J.
