根据匀强电场中两点间电势差大小与这两点沿电场方向的距离大小成正比,可得出推论(1):匀强电场中任意一条直线上两点间电势差大小之比等于直线上
According to the ratio of the potential difference between two points in a homogeneous electric field is proportional to the distance between these two points along the direction of the electric field, we can draw the corollary (1): the ratio of the potential difference between two points on any straight line in a uniform electric field is equal to the straight line.
