Column-I gives certain physical terms associated with flow of current through a metallic conductor.

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"}{"ne"^2"p"}`
(B) Electrical Resistivity (Q) `"nev"_d`
(C) Relaxation Period (R) `\frac{"eE"}{"m"}` τ
(D) Current Density (S) `\frac{"E"}{"J"}`

(1) (A) - (R), (B) - (Q), (C) - (S), (D) - (P)
(2) (A) - (R), (B) - (S), (C) - (P), (D) - (Q)
(3) (A) - (R), (B) - (S), (C) - (Q), (D) - (P)
(4) (A) - (R), (B) - (P), (C) - (S), (D) - (Q)

Option 2 is the Correct answer.
