What is meant by drift velocity derive relation between current density and drift velocity

Answers

Answered by mdnomanahmad

Drift velocity is the velocity ofelectrons in the presence of an external electric field. This velocity is very less(10 to the power of -4) When we say current passes through a wire, the energy is supplied through the wire. Electrons act as messenger totransfer this energy.
