A charged capacitor and an inductor are connected in series. At time t = 0 the current is zero, but the capacitor is charged. If T is the period of the resulting oscillations, the next time, after t = 0 that the energy stored in the magnetic field of the inductor is a maximum is:
A) T
B) T/4
C) T/2
D) T/1
E) 2T

Question

Quizplus · Accepted Answer

In an LC circuit, the energy oscillates between the capacitor and the inductor. The energy stored in the magnetic field of the inductor is maximum when the capacitor is fully discharged, which occurs at T/4.
