Question

What do you understand by resistivity of a conductor? Discuss its temperature dependence for
1. Metallic conductor.
2.semiconductor.
3. Ionic conductor.
4. Electrolyte .
5 Insulator​

Answer 1

resistivity is just invertly proportional to the temperature

on increasing temp resistivity decrease here option 1,2,3 are increases on increasing temperature but option 4,5 decrease
