Capacitor in Electronics – What It Is and What It Does
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

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.
