What is a Capacitor? A capacitor is an electrical energy storage device made up of two plates that are as close to each other as possible without touching, which store energy in an electric field. They are usually two-terminal devices and their symbol represents the idea of two plates held closely together.
From energy storage and voltage regulation to signal filtering, circuit protection, and timing and oscillation, capacitors play a vital role in ensuring the proper operation and performance of electronic systems. Understanding the functions of capacitors is essential for anyone involved in electronic design or troubleshooting.
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.
Charging and Discharging: The capacitor charges when connected to a voltage source and discharges through a load when the source is removed. Capacitor in a DC Circuit: In a DC circuit, a capacitor initially allows current flow but eventually stops it once fully charged.
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.
