Relation between Current density and Electric Field is given by...

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \dag \: \underline{ \boxed{ \bold{ \rm{ \pink{E = J \rho}}}}} \: \dag \\ \\ \therefore \rm \: \frac{J}{E} = \frac{1}{ \rho} \\ \\ \implies \rm \: we \: know \: that \: \red{ \frac{1}{ \rho} = \sigma} \\ \\ \therefore \: \underline{ \boxed{ \bold{ \rm{ \orange{ \frac{J}{ E} = \sigma = conductivity}}}}}$
