B	Electrical Resistivity
C	Relaxation Period
D	Current Density

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

Answer 1

Answer: (A)

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

Answer 2

$j = neV _{ d }=\sigma E$
$\sigma= j / E$
$\Rightarrow \rho= E / j$
$( A ) \rightarrow( R )$
$( B ) \rightarrow( S )$
$( C ) \rightarrow( P )$
$( D ) \rightarrow( Q )$
