A resistor divider (see diagram) divides a larger voltage into a smaller
mVout = (mVin * R2) / (R1 + R2)
This program generates a table of resistor pairs for your circuit. Click here to return to retrofreedom.com homepage
Sometimes, you want to precisely tune a signal and to do that, you might use a resistor divider. Other resistor divider calculators exist, but they usually give you the most ideal values. In the real world, resistors come in fixed sizes. With this web application, you can give a voltage and a desired output voltage, where you will then be given a precisely calculated list of resistor combinations to use, for actual real world resistor values, in your divider circuit. To my knowledge, no other such program existed, simple though it may be. My name is Leah Rowe, and you can learn more about me from my personal website at https//vimuser.org/.
