It is defined as average speed with which free electrons get drifted towards the positive end of the conductor under the influece of an external electric field . Drift speed (velocity) of electrons is given by Vd = i/nAewhere i is the current in amperesn is the no. of electrons per unit volumeA is the area of cross sectione is the electronic charge
It means the velocity..

The velocity gained by the accelerating electrons in uniform electric field inside the conductor is drift velocity. The average velocity, acquired by free electrons along the length of a metallic conductor, due to existing electric field is called drift velocity.\xa0Let ‘n’ be the number density of free electrons in a conductor of length ‘l’ and area of cross-section ‘A’.\xa0Total charge in the conductor, Q = Ne = (nAl)eTime taken, t is given by,\xa0Therefore, the current flowing across the conductor is given by,\xa0That is,\xa0, which is the amount of current flowing through a conductor in terms of drift velocity.

The speed in which we can drift perfect for at least 500 meters is call drift speed.(If this is about cars so thi sits right and if it is about something else forgive me).Minimium drift speed is 80kmph
\t\xa0\tThere are always some free electrons inside any metal at room temperature .There will be some free electrons. these free electron inside the move randomly and collide frequently with heavier atoms and change their direction of motion at every time.When a steady electric field is applied to conductor, the electrons start moving towards the positive terminal of applied electrical potential difference but this movement of electrons doesn\’t happen in straightway. During travelling towards the positive potential the electrons continuously collide with the atoms and bounced back in a random fashion. During the collision the electrons lose some\xa0of their kinetic energy and again due to the presence of electric field, they are re-accelerated towards the positive potential and regain their kinetic energy. Again, during further collision the electrons partly lose their kinetic energy in the same manner. Thus the applied electric field cannot stop the random motion of the electrons inside a conductor.\xa0Although in presence of applied electric field, the motion of the electrons is still random, but there will be over all resultant movement of electrons towards positive terminals. In other words, the applied electric field makes the electrons to drift towards positive terminal. That means the electrons get an average\xa0drift velocity.\tdrift velocity is denoted by\xa0u,\tu=μe\u200bE= I\u200b/ nAQ
