The Fundamentals of Capacitors in AC Circuits
An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric between the two plates, so it is a displacement current that the ammeter records. The value of this current is affected by the applied voltage, the supply frequency, and the capacity of the capacitor.
