A Deduction Method of Electric Potential Multipole Expansion
Jianping Liu · Journal of Southwest China Normal University · 2010
This paper puts forward a deduction method of electric potential multipole expansion:analyses first the electric potential produced by electric-dipoles,coaxial electric four molecules and the electric eight-pole,and then exchange the electric potential produced by any electric charge infinitesimal of the electrified body with the addend of the electric potential produced by electric multiple molecules such as coaxial electric charge unit,electric-dipoles,electric four molecules,electric eight-pole of equal value,so the multipole expansion of electric potential can be obtained.
