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.
Formula for calculating drift velocity of electron in a conductor of constant cross-sectional area is given by
V = 1/ nAq
Where, ‘v’ is the drift velocity of the electrons
‘I’ is the current flowing through the conductor (amperes)
‘A’ is the cross-section area of the conductor (m2)
‘q’ is the charge on the charge carrier (coulombs, c)
