Parallel Resistance Calculator

12 parallel resistor calculator

Does anybody know where I can download the following calculator.

It calculates the two resistors in parallel given the final resistance value and the set require (e.g. E12)

1) I input the Resistance Value that I require.
2) I input the resistor set to be used E12

3) The calculator gives me the nearest two resistor values I require to put in parallel to obtain the required resistance (or as near as can be).

Thanks in advance.

calculator for parallel resistors

Just put the formula in excel sheet with your specification and u will get the desired result.

parallel resistor calculator e12

just write a c code........
store the resistor values corresponding to the set in arrays and just use all the resistor values in combination in and check for the minimum of the difference between the obtained value and required value.........

Are you sure that Excel will work out all the combinations and permutations to give me the best fit?

(I am asking for the two resistor values I am NOT asking of the calculation.)

I don't want to reinvent the wheel.

(The question does ask Does anybody know where I can DOWNLOAD the following calculator. I know one exists on the web but it was removed. I could not download it.)

By the way there are lots of programs that could be written in many different languages.

There was a discussion on the sci.electronics.basics newsgroup a while ago. I've managed to dig it out:

Simply design a application in vb with predefined values of resistors. the program should select the best & nearst available value resistors
