静电计是静电学中常用实验仪器,由验电器改装而来,其构造和用途是怎样的?静电计可测量电势差或导体间的电势,与电压表有何区别呢?有部分同学可能不理解,故作以下分析。一、静电计也叫指针式验电器。把金箔验电器
The electrometer is a commonly used experimental instrument in electrostatics. It is reconstructed by an electroscope. What is its structure and purpose? The electrometer can measure the potential difference or the potential between the conductors. What is the difference between the electrometer and the voltmeter? Some students may not understand it. , for the following analysis. First, the electrometer is also called pointer electroscope. Gold foil electroscope
