| Abstract: | With the method of images,the mirror image of a uniformly charged ring in a conducting sphere is studied.According to character and additive formula of Legendre polynomial,space electric field distribution of a system consisting of a charged ring and conducting sphere is calculated by superposition principle.This method is easily understood,and is applied to solving the distribution of axial symmetric static field. |

| Keywords: | superposition principle of electric potential charged ring conducting sphere method of images |
