The Fundamentals of Capacitors in AC Circuits

The value of this current is affected by the applied voltage, the supply frequency, and the capacity of the capacitor. Since a capacitor reacts when connected to ac, as shown by these three factors, it is said to have the property of reactance — called capacitive reactance.
