In this post, you will find solved Numericals on drift velocity for class 12. These numerical problems are based on the drift velocity of electrons and electric current.
drift velocity of electrons
Most charge carriers, like electrons, move slowly. how the Small drift speed of electrons causes a high-speed electric current?
Here we will derive the equation showing the relationship between current and drift velocity. The drift velocity is the average velocity of the free charges and it is in the direction opposite to the electric field for electrons.
