| 摘 要： | 在部分教材和文献中,出现了关于电容器的两个错误结论:a.电容器的电容与除有效表面之外的另外两个表面有关;b.电容器的电容与接地无关.为了解决这两个问题,使用导体系的部分电容理论分析了两个错误结论产生的原因,并给出了正确的结论,所得结论对电容器的教学和使用具有较大的参考价值.此外分析过程还表明导体系的部分电容理论是分析电...

| Abstract: | There are two wrong conclusions about capacitors in some books and papers,and the conclusions are as follow: a.The capacitance of a capacitor is relevant to the non-valid surfaces of the capacitor.b.The capacitance of a capacitor is irrelevant to earth connection of the capacitor.In order to solve the two problems,the wrong conclusions are analyzed and the corresponding correct conclusions are given using the theory of the partition capacitance of the system of conductors.The correct conclusions have much r... |
