# Electric Conductivity

Written by Jerry Ratzlaff on . Posted in Electrical Engineering

Electric conductivity, abbreviated as G, is the amount of current that a material can conduct.  Depending on the material, the transfer rate will vary.  Lower the resistance, higher the conductivity.  Higher the resistance, lower the conductivity.

## Electric Conductivity formula

 $$\large{ \gamma = \frac{ I }{ R } }$$

### Where:

 Units English Metric $$\large{ \sigma }$$ (Greek symbol sigma) = electric conductivity - $$\large{\frac{S}{m}}$$ $$\large{ R }$$ = electric resistance $$\large{\frac{V}{I}}$$ $$\large{\Omega}$$ $$\large{ I }$$ = electric current $$\large{\frac{V}{R}}$$ $$\large{I}$$
