A capacitor is an electronic component to store electric charge. It is a passive electronic component that can store energy in the electric field between a pair of conductors called “Plates”. In simple words, we can say that a capacitor is a component to store and release electricity, generally as the result of a chemical action.
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.
Capacitors are fundamental in electrical systems, primarily for storing and releasing energy. They serve as essential components in electronics, power networks, and applications where temporary energy storage and stabilization are crucial. Additionally, capacitors play a key role in filtering, power conditioning, and circuit tuning.
When a voltage is applied to a capacitor, it starts charging up, storing electrical energy in the form of electrons on one of the plates. The other plate becomes positively charged to balance things out. This charge separation creates a voltage potential between the two plates and an electric field between the plates, storing the energy.
The main function of a capacitor is to store electric energy in an electric field and release this energy to the circuit as and when required. It also allows to pass only AC Current and NOT DC Current. The formula for total capacitance in a parallel circuit is: CT=C1+C2…+Cn.
The ratio of the electric charge (Q) accumulated on the electrode to the applied voltage (V) is called the capacitance (C) of the capacitor. Capacitance is an index of the ability of an electrode to store an electric charge, and the unit called farad (abbreviated as F) is used in honor of the British physicist Michael Faraday.
