在高中物理选修3-1第一章第七节中,研究平行板电容器的电容时,用到了静电计,不少学生认为静电计就是验电器.为了帮助学生进一步了解二者的区别,从以下几点论述:它们结构确实很像,静电计中金属杆下部的水平轴上装有金属指针,指针可以绕水平轴 In high school physics elective 3-1 Chapter VII section, the capacitance of parallel plate capacitors, the use of the electrometer, many students think that the electrometer is the electroscope.In order to help students learn more about the difference between the two, from the following A few discussions: They are really like the structure, electrometer in the lower part of the metal shaft with a metal pointer on the horizontal axis, the pointer can be around the horizontal axis
