一、引言在高中教材中,平行板电容器这样引入:在两个相距很近的平行金属板中间夹上一层绝缘物质,就组成一个最简单的电容器,叫做平行板电容器.把平行板电容器与一个电源相连进行充电,电容器两极板就充上等量异种电荷.充电后电容器的两板间有电势差,这个电势差跟电容器所带的电荷量Q有关.实验表明,一个电容器所带的电荷量Q与电容器两极间的电势差U成正比,我们把比值Q/U定义为电容器的电
I. INTRODUCTION In high school teaching materials, parallel plate capacitors are introduced by sandwiching an insulating material between two closely spaced parallel metal plates to form one of the simplest capacitors called a parallel plate capacitor. A power connected to charge, the capacitor plate charged with the same amount of heterogeneous charge. After charging the capacitor potential difference between the two plates, the potential difference with the capacitor charge Q. Experiments show that the charge carried by a capacitor Q And the potential difference between the two poles of the capacitor U is proportional to, we define the ratio Q / U as the capacitor
