Capacitors such as Electrolytic and Tantalum capacitors exhibit polarity due to their construction and the chemical processes involved in charge storage. A reverse-bias voltage exceeding 1 to 1.5 V can lead to electrochemical reduction of the dielectric material, resulting in short circuits and potential explosions. This phenomenon is rooted in the chemistry of the electrolyte used in these capacitors, which necessitates a specific orientation for proper operation.
