Two resistors A a A. ρ_A > ρ_B

B. ρ_A = ρ_B

C. ρ_A < ρ_B

D. The information is not sufficient to find the relation between ρ_A and ρ_B.

Given :

Resistance of resistor A, R_A< Resistance of resistor B, R_B

Formula used : Resistance is given by the formula

Where

R is the resistance

ρ is the resistivity

l is the length

A is the area of cross section

Resistance is

Resistance is

Only the relation between resistance values of and is given. R is depends on ρ, l and With the information given we cannot conclude the relation between resistivity of the two resistors.

If information about ρ, l and A is given then we can say the relation between ρ_A and ρ_B. So option D is correct.
