在匀强电场中,由匀强电场场强公式E=dU知道在电场方向上相同间距的两点间电势差相等.由几何知识我们不难证明沿任意一个方向电势降落都是均匀的,故在任一直线上相同间距两点间的电势差也是相等的;进一步推导我们还可以得到这样的结论:在匀强电场中,相互平行的相等的线段两端点电势差相等.如果把某两点间的距离等分成n段,则每段两端
In the uniform electric field, the uniform electric field strength formula E = dU knows that the electric potential difference between two points of the same pitch in the electric field direction is equal. From the geometric knowledge, we can easily prove that the electric potential drop is uniform along any direction, We can also get the conclusion that in a uniform electric field, the potential difference between the two ends of equal parallel lines is equal, if the distance between two points is equal Divided into n segments, each segment ends
