“伏安法测电阻”是中学电学中的一个基本实验。它不仅要求学生掌握实验操作,而且要求学生根据实验要求正确选择器材和设计实验电路。这个实验检查学生对学过知识的掌握情况,考查学生联系实际的能力,是近年考题中出现频率较高的题型之一。但学生对这类题目的解决往往缺乏正确的思路和方法,感到“束手无策”、“无从下手”。为此,本文讨论“伏安法测电阻”实验设计中的分析方法和步骤 “Volt-ampere measurement resistance” is a basic experiment in middle school electricity. It not only requires students to master the experimental operation, but also requires students to correctly select equipment and design the experimental circuit according to experimental requirements. This experiment examines students’ mastery of learned knowledge and examines students’ ability to relate to reality. It is one of the frequently asked questions in recent exams. However, students often lack the correct ideas and methods for solving such problems, and feel that they are “incapable of doing anything” and “having no way to start”. For this purpose, this article discusses the analysis methods and steps in the experimental design of the “voltammetric resistance measuring resistor”.
