“电阻的测量”是中学电学实验中的一个基础但极其重要的实验,由于其对学生的双基与能力的检测都非常广泛,而且多数电学实验均可涉入该问题,因而在高考中是一类出现频率极高的问题.本文从电阻的测量原理入手来探讨分析该类问题的方法,以供师生参阅.一、部分电路欧姆定律即伏安法测量电阻 “Measurement of resistance” is a basic but extremely important experiment in the middle school electrical experiment. Because it detects a wide range of students’ dual-basis and ability, and most electrical experiments can be involved in this problem, it is in the college entrance examination. This is a class of high frequency problems. This paper starts with the measurement principle of resistance to discuss the method of analysis of this type of problem, for teachers and students to refer to. A part of the circuit Ohm’s law is measured by the voltammetry resistance
