Instantaneous discharge of large-capacity capacitors
Episode 129: Discharge of a capacitor | IOPSpark
When the switch is in position A, the capacitor C gains a charge Q 0 so that the pd across the capacitor V 0 equals the battery emf. When the switch is moved to position B, the discharge process begins. Suppose that at a time t, the charge has fallen to Q, the pd is V and there is a current I flowing as shown. flowing as shown.

AC Capacitance and Capacitive Reactance
Capacitors store energy on their conductive plates in the form of an electrical charge. The amount of charge, (Q) stored in a capacitor is linearly proportional to the voltage across the plates. Thus AC capacitance is a measure of the capacity a capacitor has for storing electric charge when connected to a sinusoidal AC supply.
