An electric current carries electrons from an area of high  potential to another area of low potential. Potential difference is  the condition that must exist for a current â¦ to move electrons  around.
Electron current is the flow of electrons and, since electrons have the property of negative electric charge, an electron current is necessarily a flow of charge, i.e., an electric current (in the opposite direction of the electric current).lectric charge must be carried be something. The direction of flow of positive charge is taken to be the direction of electric current. Thus, a flow of negative charge contributes to an electric current in the opposite direction.
