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.

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.
