1 Farad: A Unit of Electrical Capacitance

The farad (symbol: F) is the SI unit of electrical capacitance. It is named after the English physicist Michael Faraday. One farad is the capacitance of a capacitor that stores one coulomb of charge when one volt is applied across it.

Capacitors are devices that store electrical energy in an electric field. They are used in a wide variety of electronic circuits, including power supplies, filters, and timing circuits. The capacitance of a capacitor is determined by the size and shape of its plates, the distance between its plates, and the material between its plates.

The farad is a very large unit of capacitance. In practice, capacitors are often measured in microfarads (µF), nanofarads (nF), or picofarads (pF).
