摘要
用微积分方法导出均匀带电圆弧在圆心处的电场强度和电势,进而讨论了几种带电圆弧组合在圆心处电场强度和电势。
The paper uses calculus to derive the electric field strength and potential at the circle center of a uniformly charged circle,and then discusses the electric field strength and electric potential at the center of several electric arc combination.
