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.
