farad

[ far-uhd, -ad ]

noun

, Electricity.

1. the standard unit of capacitance in the International System of Units (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. : F

farad

/ ˈfærəd; -æd /

noun

1. 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

farad

/ făr′əd /

1. 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.
