What is the stored energy in a 0.50-mH coil carrying a current of 4.0 A? A)2.0 x 10^-3 J B)4.0 x 10^-3 J C)8.0 x 10^-3 J D)12 x 10^-3J

Question

Quizplus · Accepted Answer

The stored energy 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 case, L = 0.50 mH = 0.00050 H and I = 4.0 A, so the stored energy is E = 1/2 * 0.00050 H * (4.0 A)^2 = 4.0 x 10^-3 J.
