关于自感系数计算问题的讨论

Discussion on the calculation of self-induction coefficient

在自感系数的计算过程中常常会出现一些错误 ,以螺线管和同轴电缆的自感系数的计算为例进行了讨论 ,得出了螺线管的自感系数不等于各匝自感系数之和的结论 ,分析了同轴电缆自感系数的计算中常易混淆的问题 .

There are some mistakes in the calculation of self -induction coefficient. This paper discusses two common questions. The self-induction coefficient of spiral winding is not equal to the sum of each circle. The confusing questions in the calculation of self -induction coefficient of the same axis cable are analysed.
