In Class 12 Physics (Current Electricity chapter), Conductance is the opposite concept of Resistance. A good conductor has high conductance.
Conductance (G): Reciprocal of resistance (G = 1/R).
SI Unit: Siemens (S), also called Mho.
Symbol: S.
High conductance = Low resistance (good conductor).
Conductance (G) is the measure of how easily electric current flows through a conductor.
The SI unit of Conductance is the Siemens (S), named after the German engineer Ernst Werner von Siemens.
Example: If a wire has resistance R = 5 Ω, its conductance G = 1/5 = 0.2 S (Siemens).
The SI unit of conductance is the Siemens (S), also called the Mho. It is the reciprocal of resistance (G = 1/R).
