Electrical work is the work done on a charged particle by an electric field. The equation for 'electrical' work is equivalent to that of 'mechanical' work: : where :''Q'' is the charge of the particle, q, the unit charge :''E'' is the electric field, which at a location is the force at that location divided by a unit ('test') charge :''FE'' is the Coulomb (electric) force :''r'' is the displacement :'''' is the dot product The electrical work per unit of charge, when moving a negligible test charge between two points, is defined as the voltage between those points. ==Overview== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Work (electrical)」の詳細全文を読む スポンサード リンク
