A metal wire is subjected to a constant potential difference. When the temperature of the metal wire increases, the drift velocity of the electron in It ______________.
Fill in the blank with the correct answer from the options given below.

Correct option is D

The drift velocity of electrons in a wire is inversely proportional to the resistance of the wire. Therefore, as the resistance increases with temperature, the drift velocity decreases. The drift velocity of electrons is much smaller than their thermal velocity. As the temperatures increases, the KE of electron increases, so the thermal velocity will increase
