伏安法测电阻实验中减少误差的几种方法

摘要

由于电表内阻的存在,故用传统的伏安法测电阻时会产生误差,为了减少测量误差,利用几种改进后的方法进行测量,测量过程简便、结果准确。%Because of the internal resistance of the electrometer,traditional resistance measurement with voltmeter-ammeter method tends to generate errors.In order to reduce measurement errors,some improved methods for measuring resistance are introduced in this paper,which leads to a more accurate result and simpler measurement process.
