Capacitor representation method
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.
