Capacitor

Capacitor is a device that can store energy in the electric field, by collecting an internal imbalance of electric charge. Capacitor has units called farads. Discovered by Michael Faraday (1791-1867). Capacitors are now also known as the "capacitor", but the word "condenser" is still used today. First mentioned by the Italian scientist Alessandro Volta in 1782 (from the Italian condensatore), with regard to the ability of the appliance to store a high electrical charge than other components.
