There are several factors that affect the resistance of a conductor;
material e.g. copper has lower resistance than steel.
length – longer wires have greater resistance.
thickness – smaller diameter wires have greater resistance.
temperature – heating a wire increases its resistance.
What is the difference between resistance and resistivity?
The resistance of an object (i.e., a resistor ) depends on its shape and the material of which it is composed. Resistivity ρ is an intrinsic property of a material and directly proportional to the total resistance R, an extrinsic quantity that depends on the length and cross-sectional area of a resistor.
