Reversed Bias Diodes? Answered

I really want  some clarity on "reversed bias diodes"

whats the point of having a reversed bias diode? when would a person want to apply it to a circuit?

if current can't flow through it, wouldnt it just mess up the circuit?

Please shed some clarity on this subject for me, it would be greatly appreciated!

CERTAIN kinds of diode are used for their "backwards" property, specifically Zener and Avalanche diodes.

In use, the reverse biased zener is a SHUNT component, and wired in parallel with a load that requires a fixed supply voltage.

Lots of things including oscillators with few parts. I think it is call negative resistance. https://www.instructables.com/id/Ultra-simple-flasher

Diodes are the "check valve" of electricity. There are applications where current *could* be flowing both directions on a wire, but you only want to allow it to go one way. A full-rectifier circuit (a critical part of AC-to-DC conversion) is a good example.
