做好静电实验的关键是绝缘良好.潮湿的气候会使绝缘变坏,所以,在湿度较大的环境中,不采取有效措施,很多静电实验就不易成功.但有些静电实验却在气候很干燥的时候,也得不到预想的效果,甚至完全失败.一、电摆实验电摆是由支架、绝缘良好的摆线和摆球(或薄纸筒)组成.用它做电荷间的作用力和检验电荷的性质等实验.在实验时,用带电的起电棒.先给摆球带上某种电荷.正常 The key to doing a good electrostatic test is good insulation. A humid climate will make the insulation worse. Therefore, in an environment with high humidity, without taking effective measures, many electrostatic experiments are not easy to succeed. However, some electrostatic experiments are very dry. At the same time, the expected effect was not achieved or even completely failed. First, the electric pendulum experiment electric pendulum is composed of a stent, a well-insulated cycloid and a pendulum ball (or a thin paper tube). It is used to act as a force between charges. And testing the nature of the charge, etc. During the experiment, using a charged electrification bar, first give the pendulum ball some charge. Normal
