Conductivity

Conductivity, abbreviated as \( \gamma \) (Greek symbol gamma) and \( \sigma \) (Greek symbol sigma), 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. 

 

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

 

Conductivity Formula
\(\large{ J =  \frac{ J }{ E }  }\)
Symbol	English	Metric
\(\large{ \sigma }\) (Greek symbol sigma) = conductivity	-	\(\large{\frac{S}{m}}\)
\(\large{ J }\) = current density	-	\(\large{ \frac{A}{m^2}  }\)
\(\large{ E }\) = electric field	-	\(\large{\frac{V}{m}}\)
