Vedclass · Answer

(A) The drift velocity ${v_d}$ of electrons in a conductor is given by the formula: ${v_d} = \frac{eE	au}{m}$,where $e$ is the charge of an electron,$E$ is the electric field intensity,$	au$ is the relaxation time,and $m$ is the mass of the electron.Since $e$,$	au$,and $m$ are constants for a given material at a constant temperature,the drift velocity is directly proportional to the electric field intensity.Therefore,${v_d} \propto E$.

Drift velocity ${v_d}$ varies with the intensity of the electric field $E$ as per the relation:
