Please enter two resistor values, the third value will be calculated.
You can even enter the total resistance and one known resistance.
Equation for the calculation of the paralled resistances R1 and R2:
Calculation of the necessary parallel resistor, when the total resistance is known::
Notice: This calculator can also solve other math problems. Calculating resistors in parallel is
precisely the same as the calculations required for inductors in parallel or for capacitors in series.

| This calculator determines the resistance of up to 10 resistors in parallel. Enter resistances into the boxes below and when all values have been input, click on the 'calculate' button and the result will appear in the box below that button. As a test, if you enter resistances of 4, 6, and 12 ohms, the answer should be 2 ohms. Notice: Manually clearing the boxes does not reset stored values. |
