farad The derived unit of electrical capacitance in the SI system of units. One farad (F) is the capacitance of an electric capacitor between the two plates of which there appears a difference of electric potential of one volt when it is charged by a quantity of electricity equal to one coulomb (F = C/V). The unit is named after the British scientist Michael Faraday. The capaciatnce of most practical capacitors is measured in micro- or picofarads.
