Drift velocity of electrons in conductors formula in terms of field

There is an electric field in conductors that causes electrons to drift in the direction opposite to the field. The drift velocity is the average velocity of these free charges. ... The carriers of the current each have a charge q and move with a drift velocity of magnitude v.

The formula we derived for drift velocity of the free electrons is - (eE/2m) τ; where, e is the elementary charge, E is the applied electric field, m is the mass of the electron and τ is the average relaxation time for all the free electrons available in that conductor.
