耦合与谐振一直是“电路理论”课程教学中的重点和难点，这两个知识点在课堂教学中大多是单独分析讨论的。但是最近这两个知识点同时出现的一道电路考研试题给学生带来了不小的困扰。本文针对考生在求解该试题的过程中出现问题的原因进行了分析，借助相量图的应用讨论了解决办法。在“电路理论”教学中，此类知识点交叉融合问题的分析讲解将有助于学生正确理解基本概念并掌握基本分析方法。

Resonance and coupling are both key points of Electric Circuit course. They are always discussed inde- pendently in class. Many students are made confused when both of them appear together. In this paper, we analyze the problems and the causes of failure, and give another example to illustrate the method of solving such problems with phasor diagram. All of these discussions will help students to understand resonance with coupling inductance properly. It can also afford our teachers a salutary lesson in teaching knowledge points mixed together.
