What is drift velocity of electron?
It is the speed,,with which electrons move after an electric field is applied across a conductor..
It is actually an constant "average" speed with which an electron moves under the influence of an E field in a material. Under the influence of E field,the electron will try to accelerate, but due to collision with other electrons,it is not able to accelerate to a very large distance and has to start all over again.So it is never able to attain a very high speed. Its speed remains within a limited range over which we define "drift velocity" which is nothing but an average velocity over this range.
True,,and it is due to this,,that the potential energy of electron due to its movement in a potential difference,,converts into heat energy(of collision),,,and the kinetic energy remains constant..:)
Drift velocity of electron is the random motion in random direction in metal conductor before connected to a potential emf source.
sorry but i think drift velocity is not random but in the direction of electric field applied,, and when no potential is applied to the conductor,then electrons move in a randomised way..but i think thats not the drift velocity!
