• 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 E surface. 0 is the electric field without dielectric.
Distance between the surface of the capacitor is inversely proportional to its capacitance i.e., a higher distance between the surfaces implies a lesser capacitance of the capacitor. If the capacitance of a capacitor is C and the distance between the surface is d then, C ∝ 1/d Area of the Surfaces
So, in summary, as the distance between two capacitor plates decreases, the capacitance increases because the electric field between the plates becomes stronger, resulting in more polarisation of the dielectric material and a greater charge imbalance on the plates.
To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates.
The amount of charge that a capacitor can store is determined by its capacitance, which is measured in farads (F). The capacitance of a capacitor depends on the surface area of its plates, the distance between them, and the dielectric constant of the material between them. Capacitors are used in a variety of electrical and electronic circuits.
As distance between two capacitor plates decreases, capacitance increases - given that the dielectric and area of the capacitor plates remain the same. So, why does this occur? As distance between two capacitor plates decreases, capacitance increases - given that the dielectric and area of the capacitor plates remain the same.

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.

If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the attraction is stronger the closer they are.
