Goals
This utility helps designers of circuit involving voltage divider to choose a pair of resistors from a discrete set of values that best satisfy certain design equation.
Features
 User defined an arbitrary design equation in the form of "f(R1,R2)=target_value" where f(R1,R2) is an expression or function containing two resistive variables R1, R2.
 User can specify the constraints for R1, R2 in form of a logical expression.
 Standard resistance values come from one of the industry standards: EIA6, EIA12, EIA24, EIA48, EIA96, or EIA192.
 A number (set by the user) of resistance pairs are returned and sorted by the order of increasing error deviating from the target value.
The Applet and User's Guide
 Enter the design equation, such as the one used in a voltage regulator with adjustable output voltage
 Enter the constraint for the two resistors
 Choose the set of standard resistance values and change the range when necessary. Click "Refresh R Set" to view the available resistance values
 Set the number of choices to be returned, then click "Calculate"
