Question

drive drift velocity in terms of relaxation time​

Answer 1

Answer:

drift velocity is just the average velocity of the charge carriers in the conductor .So, drift velocity is proportional to relaxation time

Answer 2

Let's derive the drift velocity formula (v = eEt/m), in terms of relaxation time. Drift velocity is the average velocity with which, the electrons drift in the opposite direction of the field. We start with the acceleration of the electrons, a = F/m = eE/m.
