惠斯通电桥桥臂电阻取值范围的分析与研究

Analysis and Study on the Wheatston Bridge Experiment

分析了自组单臂电桥测量中值电阻时 ,比率臂 (R2R3)中R2 、R3 的取值与测量结果的关系 .通过多次实验数据分析 ,找出较合理的取值范围 .

Through analysing on the results of weaststone bridge experiment,author advised an efficient methode to decide the valve of R 2 and R 3.It makes the measure of R x more convienieney and accurocy.
