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 applied..
E =V/l...
... ...
F= -e E..
... ...
a = -eE/m..
... ... ...
v1 =u1+a .t1. ..(t1=time elapsed t is tau..)
similarly...
