欧姆定律测电阻实验又称伏安法测电阻。该实验目前在中学和大学里都做。它具有丰富的内容,对不同的对象,可以做不同要求的内容。但一般对该实验的分析较少,而这些分析对于选购仪器和合理搭配仪器是很重要的。此外,由于所用数学知识不深,物理概念清楚,在教师指导下,也可作为课余 Ohm’s law resistance test is also called voltammetry resistance measurement. The experiment is currently done in both the middle school and university. It has rich content, and can make different requirements for different objects. However, the analysis of this experiment is generally less, and these analyses are very important for the purchase of instruments and reasonable collocation of instruments. In addition, since the mathematics knowledge used is not deep and the physical concept is clear, under the guidance of the teacher, it can also be used as a spare time.
