摘要
文章针对目前物理教学演示实验中普遍存在的“验电器验电器到底是测量什么的仪器”这一问题的争论,通过计算进行分析,得出“指针张角的大小,如能反映电量的多少,不一定能反映电势高低;如能反映电势高低,也不一定能反映电量的多少”这一结论,从而说明验电器是既能测量电势差又能测量电量的仪器.
Aiming at the discussion about what kind of instrument the electroscope is in the physics demonstrative experiments at present, on the basis of calculation and analysis, this paper puts forward the idea that the electroscope is such a kind of instrument as can be used to measure both electric potential difference and electric quantity.
