Question

define resistance and resistivity and also give the relation between them explain the dependence of resistance on temperature​

Answer 1

Explanation:

Resistance is a measure of the opposition to current flow in an electrical circuit.

Resistivity, electrical resistance of a conductor of unit cross-sectional area bad unit length.

Answer 2

Answer:

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