- Conductor: An object in which charge can flow in one or more directions.
- Materials made of metal are common electrical conductors.
EXPLANATION:
- In the case of the conductor, the valance band and conduction band overlap with each other. So now there is an excess of electrons in the conduction band of it.
- So, Resistance increases with an increase in temperature for conductors and vice versa.
