“测定电源的电动势和内阻”实验的误差分析

Analysis on the errors of the experiment of "measuring the power of eletromotive force and resistance"

在中学物理实验中,"测定电源的电动势和内阻"是重要的实验之一。用数学方法对本实验的误差进行分析,认为误差来源于系统误差。

＂Measuring the power of electromotive force and resistance＂ is one of the most important physical experiments in senior middle school. The paper analyzes the errors of the experimeat in a mathematical way, and thinks that they are caused by the ststematieal error.
