Capacitor
The simplest model capacitor consists of two thin parallel conductive plates separated by a dielectric with permittivity e . This model may also be used to make qualitative predictions for other device geometries. The plates are considered to extend uniformly over an area A and a charge density +-r = +-Q/A exists on their surface. Assuming that the length and width of the plates are much greater than their separation d, the electric field near the centre of the device will be uniform with the magnitude E = r/e. The voltage is defined as the line integral of the electric field between the plates
