Wondering about this circuit
StillTrying:
"Will use the 75 ohm resistor and the zener."
LOL
The "Zener Diode 9.1v 5w axial" will do it just by itself, when connected to drop 9V and not just 0.7V.
RissViss:
I was using this as my information.
https://www.allaboutcircuits.com/textbook/semiconductors/chpt-3/zener-diodes/
all the circuits had resistors.
this is not about be practical, for me this is about learning different things.
RissViss:
Just tested, using the zener diode, and the voltage is down to 8.9 volts.
thanks for the help.
more experimentation is better, never hurts to learn something new.

They're all shunt voltage regulation, which needs a resistor, yours is in series volt dropping rather than regulation.
"Just tested, using the zener diode, and the voltage is down to 8.9 volts."
If your 9V1 zener is really a 5W it won't mind dissipating the ~1W of heat at all.
RissViss:
For me this is extra information, that I can use.
Much better for me to learn with building and testing then just reading.
Now I have a way to get the voltage anywhere from 8.9 to 10.37
Electronics is way more fun when you have a power supply.
Thanks everyone for the info, if you have any other things I can do with this would be great.
