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.
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.

A variable capacitor is a capacitor whose capacitance can be varied to a certain range of values based on necessity. The two plates of the variable capacitor are made of metals where one of the plates is fixed, and the other is movable. Their main function is to fix the resonant frequency in the LC circuit. There are two types of variable frequency and they are,
