Electrical conductance is the reciprocal of electrical resistance. It is a measure of how easily electricity flows along a certain path through an electrical element. The SI derived unit of conductance is the siemens (formerly referred to as the reciprocal ohm or mho). Oliver Heaviside coined the term in September 1885.
Relation to other quantities
As mentioned, conductance is related to resistance by:
for purely resistive circuits
- G is the electrical conductance,
- R is the electrical resistance,
- I is the electric current,
- V is the voltage.
(Note: this is not true where the impedance is complex)
