关于干电池内阻测量方法的研究

STUDY ON MEASUREMENT METHOD RESISTANCE OF DRYCELLS

过去人们通常把干电池的内阻看成是一个恒量,但通过实验证明它是随电流大小而变化的量,所以过去测量干电池内阻的方法必须进行改进。本文对此进行了一些探索,其结果比较精确,符合实际。

Internal resistance of drycell has been regarded as a constant. But it has been showed the internal resistance varies with electric current, in the present paper,some more accurate experiments have done and the results are accordance with actual situation.
