Polarized capacitors often have a stripe down one side, which is the negative terminal, and the other end of the capacitor will be positive. Non-polarized capacitors are generally cylindrical in shape and do not have any

Do Capacitors Have Polarity – How Will You Tell? – Flex PCB

Polarized capacitors, such as electrolytic capacitors, have specific positive and negative terminals that must be connected correctly to prevent damage and ensure proper operation. Non-polarized capacitors, such as ceramic, film, and mica capacitors, can be connected in either direction without polarity concerns.

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.
