如何提高灵敏检流计内阻的测量精度

How to Enhance the Survey Precision of the Internal Resistance of a Sensitive Electric Current Meter

灵敏检流计内阻测量实验是电磁学实验中一个比较复杂有相当难度的实验 ,难就难在如何提高测量精度。本文结合实验教学中的实际情况对灵敏检流计内阻测量异常误差来源进行分析 。

Surveying the internal resistance of a sensitive electric current meter is a rather difficult and complicated electromagnetic experiment which is hard to get a high precision. In order to solve the problem, we analyzed the origin of unusual errors of surveying the internal resistance of a sensitive electric current meter with the practice of experiment teaching, and explore how to enhance the survey precision.
