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.
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 !

✈ 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.
