《全日制十年制学校中学物理教学大纲》中明确地指出:在《稳恒电流》部份中要进行惠斯通电桥的教学。学生要学会使用惠斯通电桥来测电阻的方法。众所周知;电桥电路这一部份知识的掌握,不仅可以大大地巩固和丰富已学得的直流电路知识,且在对电路的认识上可提高到用电势分析的阶段。要使学生掌握这一部份知识并在头脑中形成清晰的概念,用以判断、分析电路,并不是用临时增加几节课讲一下或突击分析几个题目、多背诵一条公式、多记一种
“The syllabus for physics in a full-time 10-year school middle school” clearly states that the teaching of Wheatstone Bridge is to be carried out in the part of “Constant Current”. Students learn how to use a Wheatstone bridge to measure resistance. It is well known that mastering this part of the knowledge of the bridge circuit can not only greatly consolidate and enrich the knowledge of the DC circuit that has been learned, but also increase the understanding of the circuit to the stage of potential analysis. To enable students to master this part of the knowledge and form a clear concept in the mind to judge and analyze the circuit, it is not a matter of temporarily adding a few lessons or an assault to analyze a few questions, recite a formula, and remember more.
