Explanation:

The measure of a material's ability to oppose the flow of electric current through it is called resistance and it is denoted by R.

Resistivity is defined as the resistance of a material of unit length and unit cross section area. It is denoted by ρ. It is a fundamental property of a material and tells how strongly the material is opposing the current.

The resistance is related to resistivity by the relation,

R=ρ

The resistivity of a material depends on temperature. It increases with the increase in temperature and decreases with the decrease in temperature.

Thus, the resistance of a material also increases or decreases with the increase and decrease in temperature.
