Question

What happens to the current after a capacitor has charged from a DC source?

Options

• The current remains ahead of the voltage by \[\pi/2\].

• No current flows in the circuit.

• The current is doubled.

• The current oscillates between positive and negative peak values.

Answer 1

After charging from a DC source, no current flows in the circuit. Consequently, a lamp in series with the capacitor will not glow.
