उत्तर
Drift velocity of electrons in a metallic conductor decreases with increase in temperature.
As we know,
As, we increase the temperature of the metallic conductor the collision between the electrons and ions increases, which results in the decrease in the relaxation time. so, from the equation (4)
vd ∝ r
Hence, the drift velocity decreased.
