The drift velocity of free electrons is defined as the average velocity by which the free electrons are drifted towards the positive end of the conductor under the influence of an electric field.
(The direction of the drifted electrons is opposite to the direction of an applied electric field).
Vd = I/neA.
Vd = Drift Velocity.
I = current flowing in the conductor.
E = charge of an electron.
N = number of free electrons.
A = Area of cross-section.
