Drift velocity in a current-carrying metallic ohmic conductor
Description
The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field.
In terms of the basic properties of the right-cylindrical current-carrying metallic ohmic conductor, where the charge-carriers are electrons, the drift velocity can be calculated as shown here.
