take example of conductors in conductors current is due to flow of electrons as electron flows,they suffer collosion due to which they get drifted towards the positive end thus  this  velocity acquired by the electrons is called drift velocity

take example of conductor in conductor, there are large no of free electrons. current in conductor is due to flow of free electrons

during the flow of free electrons,these electrons suffer a collosion due to collosion they get drifted towards the positive end

thus this velocity accquired by electrons in drifting towards the positive end is called drift velocity

It is defined as average speed with which free electrons get drifted towards the positive end of the conductor under the influece of an external electric field . Drift speed (velocity) of electrons is given by

  Vd = i/nAe
where i is the current in amperes
n is the no. of electrons per unit volume
A is the area of cross section
e is the electronic charge

The potential difference gives electrons a drift ,that is a small constant velocity  along the length of the wire opposite to the electric field.this average velocity of electrons is called as drift velocity of the electons.
