A Zener diode usually works
- only in reverse bias.
- at variable voltages.
- only in forward bias.
Explanation
A Zener diode performs its regulating function in reverse bias, operating in the breakdown region where it maintains a nearly constant voltage. In forward bias it simply behaves like an ordinary conducting diode. Its defining, useful operating mode is therefore reverse bias, not forward or variable voltage operation.
funcaul asking:
Please kindly explain. Also can I get a link or material where I can read up on all the modules.thanks.

If a Zener were in forward bias it would just be a diode. They are designed to work at a set voltage in reverse bias.
