Question

what happens to the resistance of a conductor when temperature. is increased ​

Answer 1

Answer:

With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current. ... Since conductors typically display an increased resistivity with temperature increase, they have a positive temperature coefficient.
