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/4
B)T/2
C)T
D)3T/2
E)2T

Question

Quizplus · Accepted Answer

In an LC circuit, the energy oscillates between the capacitor and the inductor. The energy is fully stored in the capacitor at t = 0 (maximum electric field energy) and fully in the inductor (maximum magnetic field energy) at T/4, completing a quarter of the oscillation period.
