Conductance (G) is reciprocal of resistance*. Whereas resistance of a conductor measures the opposition which it offers to the flow of current, the conductance measures the inducement which it offers to its flow.
from Eq. (i) of Art. 1.6,
where σ is called the conductivity or specific conductance of a conductor. The unit of conductance is siemens (S). Earlier, this unit was called mho. It is seen from the above equation that the conductivity of a material is given by
Hence, the unit of conductivity is siemens/meter (S/m).
