Answer:
At a given temperature
Resistivity depends only on the material and resistance depends on resisitvity, length of the wire and cross-sectional area of the wire
Explanation:
At a given temperature the resistance of a specimen with unit length and unit cross sectional area is called resisitivity.
We get
R = ρl/A
where; R = resistance
ρ = resistivity
l = length of the wire
A = cross-sectional area of the wire
So you get, ρ ∝ 1\l
ρ ∝ A
ρ ∝ R
Answer:
proportionality constant dependent on the identity of the material
