Question

How does the drift Velocity of electrons in a metallic conductor vary with increase in temperature

Answer 1

I have two answers
1) This velocity is called the drift velocity. When the temperature isincreased, the electrons become kinetically excited - or to put it simply, they move faster. Due to this, they undergo a lot more collisions. ... To sum up, drift velocity of an electron would decrease with increase in temperature.

2) No.
It would decrease. The thermal velocity of the electron would increase with the temperature. The average distance traveled by the electron between successive collisions (mean free path) being constant, the average time between collisions would decrease. This causes a decreased drift velocity as shown:
.

Answer 2

Answer:

Explanation:

Drift velocity will decrease with increase in temp as when temp increase the kinetic energy of electrons increases too due to which their no of collisions increases too and every time a electron collide it again starts moving with 0m/'s velocity due to which drift velocity also decreases
