T形和Ⅱ形电阻电路等效变换的教学探讨

Discussion on Teaching of Equivalent Transform Between Tee Interconnection and Pie Interconnection

本文给出了5种T形和Ⅱ形电阻电路等效变换公式的推导方法。它们是:基于等效定义、基于等效性质、基于能量守恒定律、基于戴维南定理和基于二端口参数矩阵等推导方法。基于这5种推导方法,笔者给出了切实可行的教学建议。本文的讨论对从事电路教学的教师具有一定的参考价值。

This paper has proposed five methods to deduce values for the T/П-connected resistors in terms of the equivalent П/T-connected resistors. The five methods are based on equivalent definition, equivalent property, law of conservation of energy, Thevenin theorem and parameter matrix of two-port. Feasible teaching suggestions have been given based on these methods. It is helpful for the teaching of circuits.
