电力线电力线electricforce，lineof图示电场分布的虚设的有向曲线族。曲线上每一点的切线方向与该点电场方向一致。电力线形象直观，不仅可以图示静电场，也可图示非稳恒时的电场以及辐射场，在物理教学和工程中广泛采用。根据电场的性质可确定电力线的若干性质：①在静电场中，电力线不闭合，起于正电荷，止于负电荷。②若孤立带电体系的正、负电荷一样多，则正电荷发出的电力线全部汇集于负电荷。③在没有电荷的空间里，电力线不相交也不中断。④电力线与等势面正交。⑤在导体附近，电力线与导体表面垂直，电力线不能起止于同一导体上。在变化磁场产生的有旋电场中，电力线环形闭合，围绕着变化磁场。电力线描绘了电场的走向和空间分布，电力线的疏密反映了各处电场的强弱，电力线还有助于了解电场的性质（如是否有源，是否有旋）。但是，分立的曲线、粗略的疏密不能准确地反映电场的连续分布和各处的强弱，电力线只是近似的图示。与电力线根数对应的严格的物理量是电通量。
