Question

how does drift velocity depend on applied voltage​

Answer 1

Answer:

vd is the drift velocity of the charge carriers. It is primarily controlled by the applied voltage, although it also depends the molecular structure of the wire. (In an ohmic device this velocity is directly proportional to applied voltage and thus provides the linear relationship between current and applied voltage.)

Explanation:

Now, if we increase the temperature, the resistance will increase resulting in decrease of current and hence drift velocity will increase. As current depends on potential, i.e., if we change it, it will definitely change the drift velocity.
