When a potential

Answer :

We know that


E=electric field

l=length of the conductor

And force on an electron is given by,

where, e=charge on electron

V=electric potential

We know that

Equating the above two equations we get,

Using 1st equation of motion

where = drift velocity

Here, u=0

t=relaxation time

Since e, V, m, l are constant.
