The Ultimate Capacitors Guide: Learn How To Use Them
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.

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.
