摘要
结合"单臂电桥测电阻"这个实验的特点提出了一个设计性实验,并给出了解决方案.在指导学生做该实验时,要求学生来完成这个设计,可以帮助学生理解单臂电桥测量电阻的原理.
Abstract A designing experiment and the relative solution have been given combined with the characteristics of the resistance measurement experiment with Wheatstone bridge. Accomplishment of this designing experiment can help students understand the principle of the resistance measurement with Wheatstone bridge.
