Question

Why does the resistance of metallic conductor increases with increase in temperature?

Answer 1

Explanation:

Beacause with the increase in temperature of conductor, the random motion of electron increases. As a result the number of collision of electron with the positive Ion increases Hence the resistance of conductor increases with increase in its temperature .

Thank you

Answer 2

Explanation:

Because as the temperature increase the number of collision of electron in the conductor is increased the resistance is increased
