Resistance and Conductance

The reciprocal of electrical resistance is conductance

The unit of electric resistance is ohm (Ω)

R = U / I                  (1)

where 

R = resistance (ohm, Ω)

U = electrical potential (volts)

I = current flow (ampere)

The reciprocal of resistance is conductance 

G = 1 / R                  (2)

where

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
