Question

define and derive drift velocity​

Answer 1

Answer:

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

Please mark me brailiest

Answer 2

Answer:

Drift Velocity Derivation

Drift Velocity Derivation Drift velocity is defined as the average velocity attained by the particles (electrons) of a given material due to an electric field which is proportional to current. Ohm's law can be expressed in terms of drift velocity as follow: u=μE.
