Question

Quizplus · Accepted Answer

The resistance of a wire does change when its temperature changes. As the temperature increases, the resistance of the wire also increases, and vice versa. This is due to the increase in collisions between the electrons and the atoms in the wire, which increases the resistance. The extent to which the resistance changes with temperature depends on the material of the wire, as each material has a different temperature coefficient of resistance.
