| Answer» An electric current that flows from positive to negative is called a conventional current.An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It is conventional to think that current flows from a higher potential to a lower potential. As the electrons are negatively charged the flow of electrons occurs from a lower potential to a higher potential. So the conventional current flows in a direction opposite to the direction of flow of electrons.The conventional direction of current is taken to be the direction of flow of positive charge, i.e. the conventional current flows from the positive to the negative of an electric cell. | |
