电容入门知识 电容就是两块导体中间夹着一块绝缘体构成的电子组件，就像三明治一样。电容是电子设备中最基础也是最重要的组件之一。电容的产量占全球电子元器件产品（其它的还有电阻、电感等）中的40 以上。基本上所有的电子设备，小到闪盘、数码相机，大到航天飞机、火箭中都可以见到它的身影。-Introduction to knowledge capacitance capacitor is two conductors in the middle of holding a piece of electronic components consisting of an insulator, like, like sandwiches. Capacitance is the most basic electronic equipment is one of the most important components. Capacitance of the total global production of electronic components products (there are other resistors, inductors, etc.) in more than 40 . Basically, all the electronic equipment, small enough to flash drives, digital cameras, as large as the space shuttle, rockets can be seen in both figure it.
