To understand drift velocity, assume that there is a conductor. And, there are n number of free electrons per m 3 of the conductor.. Let us assume that the axial drift velocity of these electrons be v meters/second. Drift velocity can be expressed in terms of Ohm’s law. u = µE. Where, u represents the drift velocity, µ represents the electron mobility, and.
The length of the flow velocity vector is the flow speed and is a scalar. From Wikipedia, The Free Encyclopedia In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero.

In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero. Wikipedia is a free online encyclopedia, created and edited by volunteers around the world and hosted by the Wikimedia Foundation. Drift velocity is the average velocity with which free electrons get drifted in a metallic conductor under the influence of electric field.

Velocity is an important concept in kinematics, the branch o classical mechanics which describes the motion o bodies. Here Vp is the drift velocity referred to the concentration of holes. µ p refers to the mobility of the concentration of holes and E representing the electric field acting upon it.

It doesn't really need updating--- it is just talking about the random directional drift of electronic velocities in the thermal skin of width kT in the metal.
