How does the drift velocity of electrons in a metal conductor vary with the increase in temperature?

Text Solution

Verified by Experts

With the increase in temperature, the drift velocity of free electons in a metal conductor decreases due to increase in collision frequency of free electorns with the atoms/ions of the conductor.
