Electric Field Between Two Parallel Plates

The Electric Field between Two Parallel Plates of a Capacitor. Before we can discuss parallel plates, we must remind ourselves about what an electric field is. An electric field (E) is a region in space in which a stationary electric charge will feel a force.

Parallel Plate Capacitor

A parallel plate capacitor is a device that uses two metal plates with the same surface area as electrodes. One plate is positive and the other is negative when a power source is applied. The plates are separated by a gap filled with a dielectric material, which doesn''t conduct electricity but can hold electrostatic charges without any energy

In a capacitor, the plates are only charged at the interface facing the other plate. That is because the "right" way to see this problem is as a polarized piece of metal where the two polarized parts are put facing one another. In principle, each charge density generates a field which is $sigma/2 epsilon$. It is just that the actual geometry

A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as

When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $${bf E}=frac{sigma}{2epsilon_0}hat{n.}$$ The factor of two in the denominator comes from the fact that there is a surface charge density on both sides of the (very thin) plates.
