There are also capacitors that only work well if you put the higher voltage on a dedicated pin. This is called a polarized capacitor. In fact, they usually blow up if you get the voltage backwards. The capacitor polarity is designated by the '' + '' symbol on one of the capacitor pins, meaning that the higher voltage should be connected there.
