Electrical Conductivity
Electrical conductivity or specific electrical conductance is the reciprocal of electrical resistivity. It is a specific property that represents the ability of a material to conduct electric current.
Notation
It is commonly denoted by \(\sigma\), \(\kappa\) (in electrical engineering) and \(\gamma\).
Formula
\(\sigma = \frac{1}{\rho}\),
where \(\rho\) is the electrical resistivity.
SI Unit
Siemens per metre (S/m)
Dimension
\(\text{M} ^ \text{-1} \text L ^ \text {-3} \text T ^ \text 3 \text I ^ \text 2\)
