| Abstract: | The electric-field intensity inside and outside of the spherical cavity in polarized homogeneous dielectric are recalculated by use of Laplace equation, and the conclusion are different from those in some textbooks. The influence and hazard of the air bubble to the insulating properties of materials are pointed out. |
