The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
Derivation of Energy Stored in Capacitor Consider a capacitor of capacitance C, which is charged to a potential difference V. The charge Q on the capacitor is given by the equation Q = CV, where C is the capacitance and V is the potential difference.
The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V
Another way to measure the capacitance is to include the unknown capacitor in a resonance circuit. The accuracy is directly dependent on the used reference inductor. Inductors with a small tolerance are rare and expensive. Fig. 11: Resonance method measuring arrangement for capacitors.
The flow of electrons onto the plates is known as the capacitors Charging Current which continues to flow until the voltage across both plates (and hence the capacitor) is equal to the applied voltage Vc. At this point the capacitor is said to be “fully charged” with electrons.

However, the potential drop (V_1 = Q/C_1) on one capacitor may be different from the potential drop (V_2 = Q/C_2) on another capacitor, because, generally, the capacitors may have different capacitances.

Photo: A small capacitor in a transistor radio circuit. A capacitor is a bit like a battery, but it has a different job to do. A battery uses chemicals to store electrical energy and release it very slowly through a circuit; sometimes (in the case of a quartz watch) it can take several years. A capacitor generally releases its energy much more rapidly—often in seconds …
