# 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

$$\large{ \gamma = \frac{ I }{ R } }$$
Symbol English Metric
$$\large{ \sigma }$$ (Greek symbol sigma) = conductivity - $$\large{\frac{S}{m}}$$
$$\large{ R }$$ = resistance $$\large{\Omega}$$ $$\large{\frac{kg-m^2}{s^3-A^2}}$$
$$\large{ I }$$ = current $$\large{I}$$ $$\large{\frac{C}{s}}$$
