Vedclass · Answer

(D) Specific conductance or conductivity $(\kappa)$ is defined as the reciprocal of specific resistance $(ho)$: $\kappa = \frac{1}{ho}$.Since $R = ho \frac{\ell}{A}$,we have $\frac{1}{ho} = \frac{1}{R} 	imes \frac{\ell}{A}$.Thus,$\kappa = G 	imes G^*$,where $G$ is conductance and $G^*$ is the cell constant.Therefore,the conductivity of a solution is defined as the conductance offered by $1 \ cm^3$ of an electrolytic solution.The $SI$ unit of $\kappa$ is $S \ cm^{-1}$ or $ohm^{-1} \ cm^{-1}$.

The electrical conductance of unit volume $(1 \ cm^3)$ of solution is called as
