How does drift velocity of electrons in ...

How does drift velocity of electrons in a metallic conductor vary with increase in temperature ? Give reason.

Text Solution

Verified by Experts

On heating a conductor its resistance increases and the current decreases. Consequently, the drift velocity of free electrons decreases.
