| Abstract: | The distribution of electric charge on the surface of a shielded conductor is analysed using the integral method. In order to solve the integral at singularity, a series of analytic formula is presented, by which complicated mathematical calculation can be avoided. A concrete example is analysed and the precision of the integral is estimated. |
