Question

explain briefly about drift velocity ? ...​

Answer 1

Answer:

Drift Velocity

Explanation:

When External Electric Field is applied in a Conductor ; the free electrons inside it start to drift towards +ve terminal of battery with uniform average velocity is called as drift Velocity .

V drift = Acceleration ( a ) × Relaxation time ( T ) = e × E × T / m

Drift Velocity relation with Electric current

Current ( I ) = n × e × A × V drift

Hope it helps you

Answer 2

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.
