Match Column - I with Column - II

Electrical conductivity of a conductor depends on temperature and nature of conductor.

Conductance of a conductor depends on dimensions (length and area of cross section), temperature and nature of conductor.

$\mathrm{G}=\frac{1}{\mathrm{\rho }}\frac{\mathrm{A}}{\mathrm{L}}$

For a given conductor and at a given temperature, current density depends on electric field strength.

$\mathrm{J}=\frac{\mathrm{E}}{\mathrm{\rho }}$

For a given potential difference applied across a conductor, current in it will depend on dimensions (length and area of cross section), temperature and nature of conductor.

$\mathrm{I}=\frac{\mathrm{V}}{\mathrm{R}}=\frac{\mathrm{VA}}{\mathrm{\rho L}}$
