非平衡桥式电路中互易定理的应用

本文介绍了将互易定理应用于非平衡桥式电路中的某支路上物理量的求解，以及对非平衡桥式电路等效电阻的求解，为等效电阻的求解提供了另一种思路。通过实例的讲解，学生可更好地掌握互易定理的使用以及等效电阻的求解，既丰富了教学内容，又开阔了学生的视野。

The Application of Reciprocity Theorem in Unbalanced Bridge Circuit

This paper introduces that reciprocal theorem can not only solve physical quantity in a barach of the un-balanced bridge circuit,and can solve equivalent resistance problem of the unbalanced bridge circuit which pro-vides another method to solve the problem of equivalent resistance. By explaining the examples,students can better grasp and use the reciprocity theorem to solve the problem of equivalent resistance,it not only enrich the teaching content,but also broaden their horizons.
