The Lower the External Characteristic of the Iron-core Transformer, the Lower the Power Factor of the Inductive Load?
感性负载功率因数越低，铁芯变压器的外特性越下降吗?。
The consistent results indicate that the former method can be used to study not only iron-core transformer, but also non-core transformer, and therefore, is a basic analytical method.
因而用自感电动势、互感电动势建立微分方程的方法既可以讨论含铁芯变压器，亦可用于对空芯变压器的探讨，因此是一个最基本的分析方法。
