Question

Write the relation between drift velocity $v_d$ and applied electric field $E$ of a conductor.

Accepted Answer

$$v_d = \frac{eE	au}{m}$$
where $e$ = charge of electron, $	au$ = relaxation time, $m$ = mass of electron.
Drift velocity is directly proportional to the applied electric field: $v_d \propto E$.
