When a potential difference V is applied across a conductor at temperature T, the drift velocity of the electrons is proportional to :
The drift velocity vd of electrons in a conductor is given by the equation:
vd = eEr/m
Since E = V/L, we get:
vd = eVr/mL
Here, vd is directly proportional to the applied potential difference
V. Thus, the correct answer is: (c) V
