Question

what is drift velocity ?and how it happens ?

Answer 1

Answer:

heya mate ☺

Drift velocity v is proportional to the current i (and electric field E) along the conductor length L. current i = V/R. The electric field E = potential difference V / length of conductor L. drift speed = i /(n e A) = σ E/(ne) = V / (L ρ n e) So drift velocity becomes half of its previous value

hope help u ❄❤

Answer 2

hyy mate here is your Answer:

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

the drift velocity is Vd = x10^ m/s = cm/hour. This slow average drift speed for electrons is tiny compared to the average electron speed associated with its internal energy.
