If I put two of the same voltage zener diodes in parallel, won't it limit the voltage to twice their individual value? I've read that it's not a good thing to do with two DIFFERENT values, because it won't work right,...if anyone has a good internet resource for electronics related questions, I'd really appreciate it!
I'm working on a couple different car projects, but honestly don't know much more than E=IR

 

It will not limit the voltage, but rather the current. Current would be split between the 2 diodes if you measured, but the voltage would be the same across if they were parallel.

hmm...so, if it doesn't limit the voltage, then why are they denoted by some value (ie. 9.1volt zener diode) as the pack says...


I am using a zener diode, because that's what 'the man' says...http://www.autospeed.com/image.html?...0376_10&REZ=mg

actually, after looking at this, it seems that 15v zener diode would be fine, because it's just being used to stabilize the power input...so, this really isn't an issue is it? heh

 

Just curious, what is this for?
P E are the basic electrical calculations
IE IR
P=power(watts), E=electromotive force(volts), I= Amperes, R=resistance(ohms)
Imagine those as triangles, P over E is I=P/E or P=IxE, as an example.
Easy to remember them as PIE and EIR (ear).

This is for a cold-junction compensating thermocouple circuit for a homemade EGT gauge. It'll just output 1mV/ēC, and I'll then use that to light up a 10 LED bar graph, that tops out at one volt, or 1000ēC...should work nicely...too bad I don't know what I'm doing
