Answer:
When a metalic conductor is heated
Explanation:
According to me,
When a metallic conductor is heated، the atoms in the metal vibrate with greater amplitude and frequency.
Due to increase in temperature, the thermal velocity of free electrons also increases. Therefore the number of collisions between free electron and atoms increases
If I am wrong then please correct me.☺️☺️
