| 摘 要： | 在电子线路工程及其教学过程中,都需要对电容器的直流电阻进行计算.然而,对一些特殊形状的电容器的直流电阻计算,普遍采用的电流密度法是比较麻烦的.本文根据电阻定义式,结合电阻的串联和并联的简洁关系,简单明了地对球冠形电容器、柱冠形电容器和正多棱柱形电容器等的直流电阻进行了计算,并给出相应的定量表达式.

| Abstract: | In the electronic circuit engineering and teaching process,it is necessary to calculate the DC resistance of the capacitor.However,for calculating the DC resistance of some special-shaped capacitors,the current density method generally used is more troublesome.In this paper,according to the definition of resistance,combining with the concise relationship between the series and parallel resistance,the DC resistances of spherical crown capacitor,cylindrical crown capacitor and positive polygonal capacitor and so on are calculated clearly and the corresponding quantitative expression is given. |
