farad n 1: the capacitance of a capacitor that has an equal and opposite charge of 1 coulomb on each plate and a voltage difference of 1 volt between the plates [syn: {farad}, {F}]
Farad \Far"ad\, n. [From Michael Faraday, the English electrician.] (Elec.) The standard unit of electrical capacity; the capacity of a condenser whose charge, having an electro-motive force of one volt, is equal to the amount of electricity which, with the same electromotive force, passes through one ohm in one second; the capacity, which, charged with one coulomb, gives an electro-motive force of one volt. [1913 Webster]
