CONDUCTANCE AND UNIT OF CONDUCTANCE - MHO

Conductance: Conductance is a measure of the ease with which the current will flow through a substance.

Conductance is usually denoted by G.

So, this is the reciprocal of resistance, 

i.e.                                

Appropriately, the unit of conductance is termed mho() i.e. the unit of resistance (ohm) spelled backwards.
