Question

Deduce the relation b/w current I flowing through the conductor and drift velocity Vd of the electrons

Answer 1

Answer:

The drift velocity is defined as the average velocity with which free electrons in a conductor get drifted under the influence of an external electric field applied across the conductor.

The relation between drift velocity of free electrons and the current flowing through the conductor is given by

Here, e is electronic charge, n is number of free electrons per unit volume in the conductor and A is its area of cross-section.
