静电为何不可用摩擦生电这事大家是知道的。两种物体一摩擦就来电,这种发电方式非常简单自然。古代人就掌握了这种发电方式:他们用毛皮摩擦琥珀,就得到静电。当然,在平常状态下,静电是不流动的,不流动就不能产生电流,而电流才能点亮灯泡,所以就算是灯泡上“沾满”静电,也不会被点亮。只有让静电流动起来,产生电流,它才有可能点亮灯泡。如果给静电一个可以流动起来的导电线路,静电就能流动起来,这样电流就有了。比如你身上有静电的时候,用手指一碰金属物
Why static electricity can not be triboelectric This is something we all know. The friction between two objects calls, this power generation is very simple and natural. The ancient people mastered this way of generating electricity: they rubbed amber with fur to get static electricity. Of course, under normal conditions, the static electricity is not flowing, no current is generated when no current flows, and the electric current can light the light bulb. Therefore, even the “stained” static electricity on the light bulb will not be lit. Only by letting the static current flow and producing current, it is possible to turn on the light bulb. If you give static a conductive line that can flow, the static electricity will flow and the current will be there. For example, when you have static electricity, touch the metal object with your finger
