The reciprocal of electrical resistance is conductance.
The unit of electric resistance is ohm (Ω)
R = U / I (1)
R = resistance (ohm, Ω)
U = electrical potential (volts)
I = current flow (ampere)
The reciprocal of resistance is conductance
G = 1 / R (2)
G = conductance (siemens, S)
Example - Conductance
Conductance of a conductor with resistance 10 Ω can be calculated as
G = 1 / ( 10 Ω)
= 0.1 siemens, S
