Voltage Divider Calculator I

Script finds best values for a given Division Ratio

Voltage Divider Calculator I. Find Optimum Resistors to place in series to create a Voltage Divider.
Changpuak Voltage Divider I

This routine finds the best values of a given range (E12, E24, E48). The solution found has minimum error, but other solutions with the same error are quite possible !

Input Voltage


Output Voltage



[Ω, kΩ, MΩ]


[Ω, kΩ, MΩ]

True Output Voltage



✈ The Math ...

... is not that complicated. The Output Voltage is the Input Voltage multiplied by the Ratio of
R2 / (R1 + R2). And yes : The javascript tries every combination.
