在静电学里,电势能(Electric potential energy)是处于电场的电荷分布所具有的势能,与电荷分布在系统内部的组态有关。电势能的单位是焦耳。电势能与电势不同。电势定义为处于电场的电荷所具有的电势能每单位电荷。电势的单位是伏特。 电势能的数值不具有绝对意义,只具有相对意义。所以,必须先设置一个电势能为零的参考系统。当物理系统内的每一个点电荷都互相分开很远(分开距离为无穷远),都相对静止不动时,这物理系统通常可以设置为电势能等于零的参考系统。假设一个物理系统里的每一个点电荷,从无穷远缓慢地被迁移到其所在位置,总共所做的机械功为

![]() ![]() Electric potential energy, or electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. An object may have electric potential energy by virtue of two key elements: its own electric charge and its relative position to other electrically charged objects. |
