It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may …
The electric field on one plate is "felt" by the other. A simple way to think about why the distance between the plates matters, is that the closer the plates are, the more strongly will the field of one plate help pull charges towards the other plate.
Capacitance of two parallel plates. The most common capacitor consists of two parallel plates. The capacitance of a parallel plate capacitor depends on the area of the plates A and their separation d.According to Gauss''s law, the electric field between the two plates is:. Since the capacitance is defined by one can see that capacitance is:. Thus you get the most capacitance …

Capacitance. As long as the quantities of charge involved are not too large, it has been observed that the amount of charge, (Q), that can be stored on a capacitor 1, is linearly proportional to the potential difference, (Delta V), between the two plates: [begin{aligned} Qpropto Delta Vend{aligned}]
If you increase the distance between the plates of a capacitor, how does the capacitance change? Doubling the distance between capacitor plates will reduce the capacitance four fold. Doubling the distance between capacitor plates will …
The two plates inside a capacitor are wired to two electrical connections on the outside called terminals, which are like thin metal legs you can hook into an electric circuit. Photo: Inside, an electrolytic capacitor is a bit like a Swiss roll. The "plates" are two very thin sheets of metal; the dielectric an oily plastic film in between them.
Q depends on the surface area of the conductor plates, while V depends on the distance between the plates and the permittivity of the dielectric between them. In storing charge, capacitors also store potential energy, which …

The parallel plate capacitor shown in Figure 4 has two identical conducting plates, each having a surface area A, separated by a distance d (with no material between the plates). When a voltage V is applied to the capacitor, it stores a charge Q, as shown.We can see how its capacitance depends on A and d by considering the characteristics of the Coulomb force.
A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates.
