derive the expression for drift velocity

Answer»

Drift velocity is defined as the average velocity with the free electrons get drifted towards the positive end of the conductor under the influence of an external electric field appliedE =V/l

F= -e E

a = -eE/mv1 =u1+a.t1 (t1=time elapsed)similarlyv2. v3. v3...vndrift velocity = -eE t/m
