Conclusion and Safety Note

So now you know a little more about capacitors. If you want to know more about this or any other electronic component, I highly recommend the excellent video series on the subject by the folks at Make magazine.

As a warning, while most capacitors only store a small amount of charge, the capacitors inside of cameras used to power the flash can store a very painful charge and capacitors inside of television sets can store a lethal charge. So take careful precaution if you plan on rooting around electronic devices.
