Customer ServiceCapacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage across their plates.

Customer ServiceThe voltage between the plates and the charge held by the plates are related by a term known as the capacitance of the capacitor. Capacitance is defined as: The larger the potential across the capacitor, the larger the magnitude of the charge held by the plates.
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The is equal to the electrostatic pressure on a surface.
The capacitance C of a parallel plate capacitor with plates each having cross sectional area A, separated by a distance d is given by C = dϵ0A, where ϵ0 is the permittivity of free space with value 8.85×10−12Fm−1. This equation assumes that the distance between the plates is much smaller than the size of the plates themselves.
However, it is a misnomer to think that the capacitance of a capacitor is defined by the amount of charge and voltage. Capacitance is defined by the geometry of the capacitor design, or particularly on the cross sectional area of the plates and the separation distance of the plates (and also the material, if any, placed between the plates).
A capacitor is typically constructed as shown in Figure 5.1. When a voltage v is applied, the source deposits a positive charge q on one plate and negative charge –q on the other. where C is the constant of proportionality, which is known as the capacitance of the capacitor. Unit for capacitance: farad (F). two plates.
Inside the capacitor the electric field points from the positively charged plate to the negatively charged plate and is perpendicular to the surface of the plates. This is equal to the potential energy at the higher potential plate, taking the potential energy at the other plate to be zero.
