GIVE THE DEFINATION OF DIFT VELOCITY

Thedrift velocityis the averagevelocitythat a particle, such as anelectron, attains due to anelectric field.

Drift velocity is expressed in the following equations:

whereis the charge density,is charge density (in unitsC/m³), andis the drift velocity, and whereis theElectron mobility(in units (m^2)/V*s) andis theelectric field(in units V/m).
