Column \(- I\) gives certain physical terms associated with flow of current through a metallic conductor. Column \(- II\) gives some mathematical relations involving electrical quantities. Match Column \(- I\) and Column \(- II\) with appropriate relations.

Column \(- I\)	Column \(- II\)
\((A)\) Drift Velocity	\((P)\) \(\frac{m}{n e^{2} \rho}\)
\((B)\) Electrical Resistivity	\((Q)\) \(\mathrm{ne} v_{\mathrm{d}}\)
\((C)\) Relaxation Period	\((R)\) \(\frac{\mathrm{eE}}{\mathrm{m}} \tau\)
\((D)\) Current Density	\((S)\) \(\frac{E}{J}\)

1. A \((A)- (\mathrm{R}),(\mathrm{B})-(\mathrm{S}),(\mathrm{C})-(\mathrm{P}),(\mathrm{D})-(\mathrm{Q})\)
2. B \((A)-(R), (B)-(S), (C)-(Q), (D)-(P)\)
