惠斯通电桥教学电路的分析

Analysis of Wheatstone bridge circuit in laboratory teaching

在惠斯通电桥原理电路的基础上,讨论了教学实验中自组电桥测量电路的仪器选择,举例分析了自组电桥测量电路的使用和测量结果,指出不同自组电桥测量电路在教学应用中的优点,为实验教学中突出教学重点而选择电路提供参考。

The simplest and typical bridge measurement circuit is the Wheatstone one and based on the measurement principle the instrument selection in the experiment teaching is discussed. The measurement results using different selfmake bridge circuits are analyzed with examples. Thus the references are provided for the circuit selection.
