The simplest type is the parallel plate capacitor, illustrated in figure 17.1. This consists of two conducting plates of area (S) separated by distance (d), with the plate separation being much smaller than the plate dimensions. Positive charge (q) resides on one plate, while negative charge -(q) resides on the other.
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The …

(Figure 4). As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls. Eventually the charge on the plates is zero and the current and potential difference are also zero - the capacitor is fully discharged.

That is, work done to move a unit charge between two points. Very close to either charged plate the electric field only depends upon the charge density on that part of the plate and is not directly dependent upon the shape or location of the second plate. The proximity of the second plate may affect the value of this charge density.
