Question

Define the terms: (a) drift speed and (b) mobility of an electron in a conductor.​

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.

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.

Answer 2

Answer:

A) the drift velocity is defined as the average velocity with which free electrons in a conductor not drifted under the influence of an external electric field applied across the conductor.

B) mobility of an electron in a conductor is defined as the ratio of it's drift velocity in a conductor to the electric field through the conductor
