A capacitor is a two terminals electronic component which stores the electric charge in the electrostatic field and discharge it back to the circuit as electrical energy. An ordinary battery consists of three essential components: a positive terminal (cathode), a negative terminal (anode), and an electrolyte.
When the plates have a voltage potential across them, they generate an electric field, which allows the capacitor to store charge. However, unlike batteries, capacitors do not produce or generate electrical energy. They merely store the charge for a short period. Capacitor Advantages and Disadvantages Advantages of Capacitors:
A capacitor is that electronic device that stores electrical energy in an electric field. It consists of two conductive plates with a gap filled with an insulating material called a dielectric.
A capacitor stores electricity as a static electric field. This is the same thing that happens when you walk across a carpet in socks and build up an electric charge, only to discharge it when you touch a door handle. You were acting as a capacitor! Inside a typical capacitor, you'll find two conductors separated by an insulating material.
A battery is smaller than a capacitor. A capacitor has lager size as compared to a battery. Battery is very costly than a capacitor. The price of a capacitor is less. Both battery and capacitor are energy-storing components utilized in electrical and gadgets building.
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can’t provide energy as quickly as it is needed.
