Electrons flow from a body that has an excess of elecrons to one that has a deficit of electrons,i.e from a body that is negativly charged to a body  that is positively charged but.........this is given in my book........but acording to potential difference electricity flows from positive charge to negative charge...howww......???plz explain me i m so confused~~

Dear Student,

The explanation given in your book is correct charge flows from higher number density to lower number density i.e. from more number of electrons (i.e. negatively charged body) to less number of electrons (i.e. positively charged body).

We know that the current flows in the opposite direction to the flow of charge. This is the reason charge flows from negative potential to positive potential (i.e. higher number of electrons site to low number of electrons site) and current flows in the opposite direction i.e. from positive to negative potential.

 Yes,your book is correct because when electrons move from an atom or molecule then atom or molecule becomes positive charged and when they move in another atom or molecule then that atom or molecule becomes negative charged due to efficiency of electrons.
