Question

what happens to the resistance of a conductor if temperature is increased

Answer 1

When the temperature of metallic conductor increases, the velocity of free electrons increases but it also cause increase in amplitude of vibration of metallic atoms (kernels) which cause some extra hindrance or resistance in the path of free electron. Hence resistance increases in investing the temperature

Answer 2

Answer:

the conductor will melt because it might have come to it's boiling point due to increase in temperature.
