Question

derive relation between current
and drif & Velocity​

Answer 1

If n is the number of free electrons per unit volume of the conductor, then the total number of free electrons in the conductor=A/n. ... Hence the current flowing through a conductor is directly proportional to the drift velocity. Explanation and Example. In a conductor there are large number of free electrons.
