| Abstract: | The energy variance of a static electric field when a dielectric of finite volume is presented under conditions of constant field source or boundary potential unchanged is discussed. The expressions of the polarization energy of the dielectric in both conditions is deduced and the difference of the physical meaning of this two expressions is pointed out. |
