Steady Electric Currents

  • Minoru Fujimoto


The macroscopic electric charge on a body is determined from the quantity of electricity carried by particles constituting the material. Although some electric phenomena were familiar before discoveries of these particles, such an origin of electricity came to our knowledge after numerous investigations of the structure of matter. Unlike the mass that represents mechanical properties, two kinds of electric charges different in sign were discovered in nature, signified by attractive and repulsive interactions between charged bodies. While electric charges can be combined as in algebraic addition, carrier particles tend to form neutral species in equilibrium states of matter, corresponding to zero of the charge in macroscopic scale.
