Answer:
<u>At a given temperature</u>
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:
resultant is a single force that can replace the of a number of forces , equililbrant is a force that is exactly opposite to resultant
