Four Resistors in Parallel Calculator
The file you download is a text file. You will have to save this text file with a html extension. When you click the html file the script will start. Enter the four resistor values as requested and note the result. If you want to calculate resistance of only two resistors in paralled Enter a very large number like 100000000000000000000 (1 with 21 zeros) for R3 and R4. If you want to calculate resistance of more than four resistors you will have to modify code by declaring variable R5 etc and subsequent relevant statements.
