The Drift velocity (Vd) and applied electric field (E) of a conductor are related as A) Vd ∝ √E B) Vd ∝ EC) Vd ∝ E2 D) Vd = Constant |

Answer» The correct option is B) Vd ∝ E. In a conductor when there is a n electric field flowing ,there is flow of electrons from one position to the another, this electrons posses a certain velocity known as drift velocity and the relation between the applied field and drift velocity is given as: Vd ∝ E From the above equations, we have found that Vd ∝ E Therefore, Electric field is proportional to the drift velocity. N is the number of electrons that are moving from one point to another. A is the area where the flow takes place. And is the velocity of electrons. |
