Abstrakt v dalším jazyce:	The perfect analogy allows solving of heat transfer problems by a lot of advanced methods of electrostatics or circuit theory for simple cases. Two quantities can be computed in principle: electric potential or electric field strength, which corresponds to two driving quantities: voltage or electric charge. The potential calculation in practical tasks needs the use of finite element method. However, if we consider the charge approach, the analytical solution can be found in several technical arrangements, or the integration can be applied successfully. This approach has many advantages against the potential one. As an important practical result, the correction factor for finite dimension plate capacitor was found. Its value is in good agreement with that given in literature. Practically, we can correct the permittivity or heat conductivity measurement in standard apparatus. In the future, the effect of material voids on thermal conductivity will be studied.
