Resistance depends on following factors: 1) Length: It is directly proportional to resistance of the conductor. 2) Area: It is inversely proportional to resistance to the cross sectional area of the conductor. 3) Temperature: It is directly proportional to resistance........

Answer:
(a) The resistance of a conductor depends on thickness (cross sectional area of the wire), length and temperature.
Resistivity is defined as the measure of the resisting power of a specified material to the flow of an electric current.
R=ρ l/a
where R = Resistance of the conductor
ρ = Resistivity of the conductor
l = length of the conductor
A = Area of cross section
i.e., ρ=R A/l
Unit of resistivity is Ωm.
