j = neV d =σ E σ= j / E ⇒ ρ= E / j ( A ) arrow( R ) ( B ) arrow( S ) ( C ) arrow( P ) ( D ) arrow( Q )

Column I		Column II
A	Drift Velocity	P	$\frac{m}{n e ^{2} ρ}$
B	Electrical Resistivity	Q	$n e v_{d}$
C	Relaxation Period	R	$\frac{e E}{m} τ$
D	Current Density	S	$\frac{E}{J}$

(A)-(R), (B)-(S), (C)-(P), (D)-(Q)

(A)-(R), (B)-(S), (C)-(Q), (D)-(P)

j=neVd​=σE σ=j/E ⇒ρ=E/j (A)→(R) (B)→(S) (C)→(P) (D)→(Q)

$j = n e V_{d} = σ E$
$σ = j / E$
$\Rightarrow ρ = E / j$
$(A) \to (R)$
$(B) \to (S)$
$(C) \to (P)$
$(D) \to (Q)$
