Defineresistance.

Answer»

Solution :(i) The resistance of a conductor can defined as the ratio between the potential difference across the ends of the conductor and the current FLOWING through it.
(ii) It is defined as the reciprocal of its resistance (R ). Hence, the conductance .G. of a conductor is given by
`G=1/R`
Its UNIT is `"OHN"^(-1)`. It is also represented as .mho.
