Explanation:
Detailed explanation-1: -Zener diodes: Zener diodes are a special kind of diode, which permits current to flow not only in the forward direction but also allow current to flow in the reverse direction when the reverse voltage is above a certain value, due to the Zener and avalanche effect.
Detailed explanation-2: -Direct current is produced when electrons flow constantly in one direction. It’s abbreviated as “DC". Since direct current flows in one direction only, its electrical pressure or voltage is always oriented in one direction, or “polarity".
