Dingfeng Capacitor---How Capacitors Work(Part 2)

When you connect a capacitor to a battery, here's what happens:
  • ●The plate on the capacitor that attaches to the negative terminal of the battery accepts electrons that the battery is producing.
  • ●The plate on the capacitor that attaches to the positive terminal of the battery loses electrons to the battery.


Once it's charged, the capacitor has the same voltage as the battery (1.5 volts on the battery means 1.5 volts on the capacitor). For a small capacitor, the capacity is small. But large capacitors can hold quite a bit of charge. You can find capacitors as big as soda cans that hold enough charge to light a flashlight bulb for a minute or more.

Even nature shows the capacitor at work in the form of lightning. One plate is the cloud, the other plate is the ground and the lightning is the charge releasing between these two "plates." Obviously, in a capacitor that large, you can hold a huge amount of charge!
Let's say you hook up a capacitor like this:
Here you have a battery, a light bulb and a capacitor. If the capacitor is pretty big, what you will notice is that, when you connect the battery, the light bulb will light up as current flows from the battery to the capacitor to charge it up. The bulb will get progressively dimmer and finally go out once the capacitor reaches its capacity. If you then remove the battery and replace it with a wire, current will flow from one plate of the capacitor to the other. The bulb will light initially and then dim as the capacitor discharges, until it is completely out.
As one of the earliest capacitor manufacturers engaged in producing capacitor for over 28 years in china , we believe one day Dingfeng Capacitor will exist in every corner of the world by means of its reliable quality and good reputation. By the way,Dingfeng sincerely welcomes all the friend to visit our company and hopes to have a good communication and double-win partnership with all of you cause dingfeng capacitor is always on the way to be better! Your views are the driving forces of DingfengI hereby on behalf of all the members of Dingfeng, thank all of you for the long-term supporting and concerning of our growth.
