The interaction energy between two charged conductors
DU Hao.The interaction energy between two charged conductors[J].College Physics,2002,21(11):3-10.
Authors:DU Hao
Abstract:The interaction energy formulas between two conductors are obtained in three cases,namely when the total charge of the conductors,the potential of the conductors and the total charge of one conductor and the potential of the other is specified.But use viewpoint of the energy of the electromagnetic field and viewpoint of the energy of the system of conductors expresses interaction energy formulas respectively.The interaction energy between two charged conductors is made up of the potential engergy,the work done in changing the conductors and energy supplied from the external source.
Keywords:interaction energy  potential energy  inter  induced
