How would I get the output voltage after placing a resister in the line? For example: 12v in plus resister (### ohms) = ##v out
I'm sure linear will come down here and post the formula here, but in the meantime, you can also check the "electronics" forum, in there there's a sticky thread with the formula in
Ohm's law, baby! V=IR. Combine it with Kirchoff's loop rule to get: V(after) = V(before) - I*R Gordon
i made a resistance calc, a resistor color calc, a resistor chart listing all the values make and a ohm calc on my page: http://www.brutal.tk look under Electronics Calculators
To calculate the resistor you need to know the current. Without a current the voltage will still be 12V. Formua as above
Might be easier basing on the resistance of the load (as I is not the rated I), then New load voltage = 12 * load resistance/(load resistance + resistor value) And load resistance = 12/rated current at 12v or 144/Rated Power
