Explain why an alternating current apparently flow through a capacitor whereas a direct current does not.

Explain why  an alternating current apparently flow through a capacitor whereas a direct current does not.

When a capacitor is connected to a d.c source, the capacitor charges fully and current stops flowing.

When the capacitor is connected to a.c voltage supply, the voltage increases and decreases alternatively. When the voltage increases the capacitor charges and when the voltage decreases the capacitor discharges. Hence continuous flow of charge (current) in the circuit.
