Definition Of Drift Velocity

Current and Drift velocity and Relation between drift veloct and current

Current||current density||drift speed

A : When a steady current flows through a conductor of non - uniform cross-section , the current density , electric field and drift velcoity do not remain constant. R : For a constant current the current density electric field and drift velocity are inversely proportional to cross - sectional area.

If A is the area of cross section of conductor, e be the charge on the electrons, n be the number of electrons per unit volume and J be the current density then drift velocity of electrons is

Define the term 'drift velocity' of electrons in a current carrying conductor. Obtain the relationship between the current density and the drift velocity of electrons.
