What is Drift velocity of electron.

Описание: Drift velocity is the average velocity with which free electrons get drifted in a metallic conductor under the influence of electric field.
The drift velocity is almost similar to that of terminal velocity gained by a while moving in a medium. The velocity is equal to electron mobility times electric field or current density divided by number carrier and charge on electron. Understanding of drift velocity is of great importance for understanding the electric current, resistance and mobility of charge carriers in metallic conductors.
This video provide detail explanation of drift velocity for charge carriers (electrons ) in metallic conductor with visual animations,Current density, number density, electric current and cross sectional area.
This topic is selected from current and electricity chapter of physics book.
