= Electrical conductance
{title2=$G=1/R$}
For an ohmic element with finite nonzero <electrical resistance> $R$, its <electrical conductance> is $G=1/R$: an <electric potential difference> $\Delta V$ drives <electric current> $I=G\Delta V$. Greater positive <electrical conductance> means a greater <electric current> for the same positive <electric potential difference>. <Electrical conductivity> is instead a bulk material coefficient relating <current density> to <electric field>.
