Question

At an instant of time during the oscillations of an LC circuit, the current is at its maximum value. At this instant, what happens to the voltage across the capacitor?

Is different from that across the inductor.It is zero.    It has its maximum value.It is impossible to determine.

Now consider an instant when the current is momentarily zero. From the same choices, describe the magnitude of the voltage across the capacitor at this instant.

Is different from that across the inductor.It is zero.    It has its maximum value.It is impossible to determine.

Explanation / Answer

1. At maximum current:
   Voltage across inductor is ZERO.

2. At zero current:
   Voltage across capacitor is maximum
