[far-uh d, -ad] /ˈfær əd, -æd/
the standard unit of capacitance in the (SI), formally defined to be the capacitance of a capacitor between the plates of which there appears a potential difference of one volt when it is charged by a quantity of electricity equal to one coulomb. Symbol: F.
(physics) the derived SI unit of electric capacitance; the capacitance of a capacitor between the plates of which a potential of 1 volt is created by a charge of 1 coulomb F
unit of electric capacity, suggested 1861, first used 1868, named for English physicist Michael Faraday (1791-1867). Related: Faradic.
farad far·ad (fār’əd, -ād’)
The unit of capacitance in the meter-kilogram-second system equal to the capacitance of a capacitor having a charge of 1 coulomb when a potential difference of 1 volt is applied.
The SI derived unit used to measure electric capacitance. A capacitor in which a stored charge of one coulomb provides an electric potential difference of one volt across its plates has a capacitance of one farad.
