Abstract: The problem of charge distribution in a constant current conductor is discussed.Based on the Hall effect,the charge distribution in the infinite cylindrical current carrying conductor is derived,and the formula of charge density in a current carrying conductor of arbitrary shape is given.

Key words: conductor, constant current, charge distribution, Hall effect, Lorentz force
