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 current is a maximum is:
A)T/4
B)T/2
C)T
D)3T/2
E)2T

Question

Quizplus · Accepted Answer

When a charged capacitor and an inductor are connected in series, they form an LC circuit, which exhibits simple harmonic motion. The current reaches its maximum value at a quarter of the period (T/4) after the system starts oscillating from the initial condition of maximum charge on the capacitor and zero current.
