The working principle revolves around the basic formula for capacitance C=εA/d, where ε is the permittivity, A is the overlapping plate area and d is the distance between plates. Any factor affecting these parameters causes the capacitance to change. For example, in linear displacement measurement, as the plate separation varies with motion, the capacitance varies
Working Principle of a Capacitor: A capacitor accumulates charge on its plates when connected to a voltage source, creating an electric field between the plates. Charging and Discharging: The capacitor charges when connected to a voltage source and discharges through a load when the source is removed.

Figure 3: Principle of parallel plate capacitor The dipole moment of the two plates will shield the charges. Therefore, it will change the effect of the dielectric medium inserted between the plates. These materials have a certain extent of permeability which is denoted by k, which is the relative permeability.
The simplest design for a capacitor is a parallel-plate, which consists of two metal plates with a gap between them: electrons are placed onto one plate (the negative plate), while an equal amount of electrons are removed from the other plate (the positive plate). Capacitors function a lot like rechargeable batteries.
This kind of capacitor can be formed by using two metals or foil plates which are placed parallel to each other. The value of capacitance of the two parallel plates is fixed by the surface area of the conductive plates and the distance between the plates. Any alteration in the values causes alteration between these two particles.
A plate in the capacitor is acquired with a certain value of charges. As the charges supplied to the plate increases it leads to the increment in the potential. Due to the increase in potential, the charges may undergo leakage. S0, to overcome such a situation another plate is placed next to the first plate which is positively charged.
