(N/A) Conductance is defined as the reciprocal of the electrical resistance of a conductor. It represents the ease with which electric current flows through a material.
Mathematically,it is given by: $G = \frac{1}{R}$
where $G$ is the conductance and $R$ is the resistance.
The $SI$ unit of conductance is the siemens $(S)$,which is also equivalent to $\Omega^{-1}$ (ohm inverse) or mho.
