Everything You Need to Know About Capacitor Polarity
By forming an insulating oxide layer on the anode of polarized capacitors, they exhibit distinct positive and negative polarities, thereby restricting the flow of current in a specific direction. In contrast, non-polarized capacitors have a relatively simple structure, consisting of two electrodes and a dielectric layer.
