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.
Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F. However, you must be careful when using an

However, the basic structure of a capacitor is a constant, which you can see below: Electrodes – these are the two conductive plates that store the energy. Dielectric – determines the capacitance and dielectric strength of the capacitor. Terminal leads – metal wires or pins which connect the capacitor to the circuit. How Does a Capacitor Work?
The governing equation for capacitor design is: In this equation, C is capacitance; ε is permittivity, a term for how well dielectric material stores an electric field; A is the parallel plate area; and d is the distance between the two conductive plates. You can split capacitor construction into two categories, non-polarized and polarized.
