Internal Resistance Measuring

Its measuring and checking included battery charge, battery capacity, battery internal resistance, circulating charge and discharge test.

电池充电试验、电池容量测量、电池内阻测量、循环充放电寿命试验。

This paper presents a new method for measuring resistance by voltametry-bridge type voltametry. It can eliminate effects of internal resistance of electrimeter without a compensator.

提出伏安法测电阻的一种新接法——桥式伏安法，该接法以电桥平衡原理为基础，不需补偿线路即可完全消除电表内阻的影响。

The process of cooperative teaching on physics and chemistry experiment, which measuring the electromotive force and internal resistance using the primary cell produced by fruit, is expatiated.

阐述了利用水果制作原电池进而测定电池的电动势和内阻的理化实验课的协同教学过程，并对教学效果进行了反馈。
