What is drift speed? |
|
Answer» 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.
