explain the theory of drift velocity
Answers
Electrons inside the conductors move along straight line and they randomly oriented. The net movement remains 0. but when an electric field is set up inside the conductor then the electrons accelerate uniformly in the direction opposite to the electric field. result of uniform accelerated motion imposes over the random motion the electrons follow curved path that is parabola.
the average of velocities attained by various electrons in the influence of electric field is called as Drift velocity
The drift velocity is defined as the average velocity with which free electrons in a conductor get drifted under the influence of an external electric field applied across the conductor . Here, m,l,n,e,and A are conductors provided that the physical conditions ( like temperature etc.) remain unchanged.
