<physics> The standard unit of electrical capacity; the capacity of a condenser whose charge, having an electromotive 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 electromotive force of one volt.

Origin: From Michael Faraday, the English electrician.
