Question

what is meant by the term Drift velocity​

Answer 1

Explanation:

HEY MATE HERE IS YOUR ANSWER

• The average velocity due to which the electrons move in a conductor under the application of an external field is called drift velocity...

• Drift velocity: It is a average velocity that a particle,such as an electron, attains in a material due to an electric field.

The formula we derived for drift velocity of the free electrons is - (eE/2m) τ; where, e is the elementary charge, E is the applied electric field, m is the mass of the electron and τ is the average relaxation time for all the free electrons available in that conductor.
