电场强度是静电学中极其重要的概念,也是高考考点分布的重点区域之一.求电场强度的方法除了常见的定义式法,点电荷场强公式法,匀强电场公式法,矢量叠加法等,还有几种特殊的思维方法.
Electric field strength is an extremely important concept in electrostatics, and it is also one of the key areas for the distribution of test sites. The methods for finding the electric field strength are in addition to the common definition methods, point charge field strength formula method, uniform electric field formula method, vector superposition method, etc. There are several special ways of thinking.
