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.

Solution & Step-by-step Explanation

Matching based on standard formulas:(A) Drift Velocity (v_{d}): v_{d} = \frac{e E}{m} τ \to (R)(B) Electrical Resistivity (ρ): ρ = \frac{E}{J} \to (S)(C) Relaxation Period (τ): From ρ = \frac{m}{n e ^{2} τ}, we get τ = \frac{m}{n e ^{2} ρ} \to (P)(D) Current Density (J): J = n e v_{d} \to (Q)The correct match is A-R, B-S, C-P, D-Q.
