The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
So the larger the capacitance, the higher is the amount of charge stored on a capacitor for the same amount of voltage. The ability of a capacitor to store a charge on its conductive plates gives it its Capacitance value.
The amount of charge Q a capacitor can store depends on two major factors—the voltage applied and the capacitor’s physical characteristics, such as its size. The capacitance of a parallel plate capacitor is C = ε0 A d, when the plates are separated by air or free space. ε0 is called the permittivity of free space.
Capacitance is defined as being that a capacitor has the capacitance of One Farad when a charge of One Coulomb is stored on the plates by a voltage of One volt. Note that capacitance, C is always positive in value and has no negative units.
The property of a capacitor that characterises its ability to store energy is called its capacitance. When energy is stored in a capacitor, an electric field exists within the capacitor. The stored energy can be associated with the electric field. Indeed, energy can be associated with the existence of an electric field.
Capacitors have the ability to store an electrical charge in the form of a voltage across themselves even when there is no circuit current flowing, giving them a sort of memory with large electrolytic type reservoir capacitors found in television sets, photo flashes and capacitor banks potentially storing a lethal charge.
