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 |
