Question

expression for druft velocity and explain the terms

Answer 1

Answer:

Derive an expression for drift velocity of free electrons. ... (ii) According to drift velocity expression, relaxation time is the time interval between successive collisions of an electron on increasing temperature, the electrons move faster and more collisions occur quickly.

Where.....

Q = charge

E = electric field

Tow = relaxation time

m = mass
