- noun the ability of a component to store electrical charge
- The property of a system that permits the storage of electronically separated charges when potential differences exist between the conductors. Expressed as a ratio of the quantity of electricity to the potential difference, usually measured in farads or microfarads.
- The ability to store electric charge between conductors which are separated by a dielectric material, when a potential difference exists between said conductors. Its value is expressed as the ratio of stored electric charge to the potential difference, and is expressed in farads, although in practicality this unit is so large that it is more common to use microfarads or picofarads. Its symbol is C. Formerly, this concept was known as capacity (4).
