State and define the S.I. unit of resistance.
The S.I. unit of resistance is ‘ohm’ (volt per ampere). The resistance of a conductor is said to be 1 ohm if a current of 1 ampere flows through it when the potential difference across it is 1 volt.
Define the term specific resistance and state its S.I. unit.
