The average velocity attained by some particle such as an electron due to the influence of an electric field is termed as the drift velocity. The movement or the motion of the particles is assumed to be along a plane and hence the motion can also be referred to as the axial drift velocity.
When conductor is subjected to an electric field E, each electron experience a force.
F=-eE
and acquires an acceleration
a = F/m = - eE/m -----(i)
Here m = mass of election, e = charge, E = electric field.
The average time difference between two consecutive collisions is known as relaxation time of election.
