Question

prove that the current density of a metallic conductor is directly proportional to the drift speed of electrons ​

Answer 1

Answer:

∴ Total number of electrons in the Conductor = Volume x electron density = Al x n . Under the influence of this field E, free electrons begin to drift in a direction opposite to that of the direction of field. where, vd is the drift velocity of electrons. Thus, current density is proportional to drift velocity.
