高中物理下册实验一、有关平行极电容器的几个实验1.如何使平板电容器带电使平板电容器带电的方法有两种,一种方法是用带电导体(如起电盘)或带电绝缘体(如带电有机玻璃)直接跟一平板接触,另一种方法是用直流电的正负极分别接到电容器的两极板上。用第一种方法使平板电容器带电时,另一块平板必须接地,才能使两极板带上等量的异种电荷(图1)。 High school physics experiment under the first volume of a few experiments on the parallel pole capacitor 1. How to make the plate capacitor is charged There are two ways to charge the plate capacitor, one method is to use live conductors (such as the power plate) or charged insulators (such as Charged plexiglass) directly with a flat-panel contact, the other method is to use DC positive and negative electrodes were connected to the capacitor plate. When the plate capacitor is charged with the first method, the other plate must be grounded to allow the plates to carry the same amount of dissimilar charges (Figure 1).
