How do Zener diodes control voltage?

Zener diodes keep voltage stable by allowing current to flow in reverse at a specific level. This video explains how they work and how Zener and avalanche breakdown help regulate voltage in circuits.
Diodes allow electricity to flow in only one direction, helping circuits work safely and correctly. This video explains how diodes block reverse current and why they are used in power supplies and ...
