摘要
根据点电荷场强公式和电场叠加原理,导出了均匀带电细圆环电场的级数表达式,进而讨论了均匀带电细圆环平面内、中心轴线上和远区的电场.
According to the formula of electric intensity of point charge and the electric field superposition principle,series expressions of electrical field generated by a uniformly charged ring were derived.Furthermore,the fields in the plane of the uniformly charged ring,at the central axis and in the distant area were discussed.
