Question

distinguish between drift velocity and mobility?

Answer 1

Explanation:

Drift velocity : It is define as the average velocity with which the free electron move toward the positive end of conductor under the influence of an external electric field across the conductor.

Mobility:

The ratio of drift velocity of the electron to the applied electric field is known as mobility.

Thank you

Answer 2

Explanation:

Drift velocity is defined as average velocity with which free electrons get drifted towards the positive end of a conductor under the influence of the external electric field.

Mobility μ is defined as the magnitude of drift velocity per unit electric field
