He also postulated that electric current flowed from positive to negative. Ever since that time it has been taught that current travels from positive to negative, especially in the automotive diagnosis and repair industry. Unfortunately, it was discovered in the late 1800's that Benjamin Franklin was wrong about the direction of current. Current is actually the movement of electrons from one atom to the other. Electron Current Theory . In 1897 the British physicist Sir Joseph J. Thomson discovered the electron and proved that electrical current was actually the movement of electrons from one atom to
