We know that Drift velocity v d =( eE / m ) τ=( e / m ) τ(( V /1)) (∵ E =( V /1)) so for a particular conductor of a particular length the drift velocity will directly depend upon voltage Hence vd propto V.

We know that Drift velocity
$v_{d} = \frac{e E}{m} τ = \frac{e}{m} τ (\frac{V}{1})$
$(∵ E = \frac{V}{1})$
so for a particular conductor of a particular length the drift velocity will directly depend upon voltage
Hence $v_{d} \propto V$ .

We know that Drift velocity vd​=meE​τ=me​τ(1V​) (∵E=1V​) so for a particular conductor of a particular length the drift velocity will directly depend upon voltage Hence vd​∝V.
