摘要
电桥法是测量电阻的常用方法,该文介绍了电桥法中的惠斯登电桥法、开尔文电桥法、比例电桥法、等臂电桥法,运用这四种方法分别对低值电阻、中值电阻、高值电阻进行实验测量。根据所得的结果进行比较分析,得到的结论是惠斯登电桥法适用于测量中、高值电阻,开尔文电桥法适用于测量低值电阻,比例电桥法适用于测量低、中、高值电阻,等臂电桥法只适用于测量中值电阻,其结果对读者有一定的参考价值。
The bridge method is a common method to measure resistance. This paper introduces the Wheaton bridge method, the Kelvin bridge method, the proportional bridge method and the equiarm bridge method. These four methods were used to experimentally measure low-value resistance, medium-value resistance, and high-value resistance. According to the obtained results, the conclusion is that the Wheatstone bridge method is suitable for measuring medium and high value resistance, the Kelvin bridge method is suitable for measuring low value resistance, the proportional bridge method is suitable for measuring low, medium and high value resistance, and the equiarm bridge method is only suitable for measuring medium value resistance. The results have certain reference value for readers.
