The SI unit of capacitance, equal to the capacitance of a capacitor between the plates of which a potential difference of 1 volt appears when it is charged with 1 coulomb of electricity.
A unit of electrical capacity. The capacity of a condenser that, charged with 1 coulomb, gives a difference of potential of 1 V. This unit is so large that 1 millionth of it has been adopted as a practical unit called a microfarad.
