高中物理课本,等势线的描绘是了解电场性质的一个重要实验,学生通过此实验把抽象的电场形象化,对理解电场的概念、电力线、等势线的分布有很大的帮助。但是,由于等势线描绘实验器配的导电纸不多,导电纸用完后又没地方购买,实验不能开出。学校实验教师提出这个问题后,我就开始找代用方法,经过实验
In high school physics textbooks, the depiction of equipotential lines is an important experiment to understand the nature of electric fields. Through this experiment, students visualize an abstract electric field, which is of great help in understanding the concept of electric fields, the distribution of power lines, and the distribution of equipotential lines. However, since the equipotential line plotter was not equipped with conductive paper, there was no place to purchase the conductive paper and the experiment could not be conducted. After the school experiment teacher asked this question, I started to find a substitute method and passed the experiment.
