Question

Define resistance and resistivity and also given relation between them

Answer 1

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. ... The resistivity of a material depends on temperature.

Answer 2

Answer:

Resistance is the measure of a material's ability to oppose the flow of electric current through it. It is denoted by R. ... Resistance of conductors increases with rise in temperaturewhile resistance of semiconductors and electrolytes decreases with rise intemperature.
