This question already has an answer here:
So i read about the Zener diode voltage regulator circuit in the
The Art of Electronics book, it made no sense to me, then I read about it in this article which was helpful but I still don't get it:
How is it reglating the voltage exactly?! and why is the diode "reverse biased" (I guess it means connected in reverse) which doesn't conduct current unless a very high reverse voltage is applied?
If for example the input voltage is 12V, what would be the output voltage and current? and what would be the voltage and current values through the diode?
