二端网络在交流电路性质分析中的应用

The Application of Two Terminal Networks in the Analysis of AC Circuit

在高职《电工基础》教材中,分析交流电路的性质时,通常以电阻、电感、电容元件串联和并联这种具有一般意义的典型电路为例,很少具体介绍混联电路,这样并不利于学生对交流电路性质分析的掌握。不论是串联、并联还是混联电路,如果将其看成是无源二端网络,从复阻抗虚部的正、负入手就可以准确判断电路的性质。

In Electrician Basis curriculum in higher vocational colleges, analyze the nature of the AC circuit, usually resistors, inductors and capacitors in series and parallel the has a general sense of the typical circuit as an example, rarely introduce hybrid circuit, so that is not conducive to students on the properties of AC circuit analysis of the master. Whether it is a series, parallel or hybrid circuit, if it is considered as a passive two terminal network, the nature of the circuit can be accurately judged from the positive and negative of the imaginary part of the complex impedance.
