Mukesh Sharma12 Years agoThedrift 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).Thanks & RegardsMukesh SharmaaskIITians Faculty
