Ans: Electrical Conductance is defined as the the ability of a conductor to conduct electric current greater the conductance more easily the current will flow, it is measured as the ratio of alternating current to the potential difference across conductor (G = I/V), It is also defined as the inverse of resistance (1/R).
SI unit of Conductance is Siemens.
Conductance Symbol: G .
