This parallel resistance calculator provides an easy method for calculating the overall resistance for two resistors connected in parallel.
Although a parallel resistor value calculation for two resistors simplifies to a simple formula, sometimes it is much easer and faster to be able to use a calculator.
To use the parallel resistors calculator, just enter the values of the parallel resistors in ohms, Ω or kΩ, etc in the two input boxes, but note all values must be in the same units, i.e. both on Ω kΩ MΩ etc.. The parallel resistor calculator will then provide the overall resistance of the two resistors in the same units as the input.
Enter the two values for the resistors, R1 and R2 in the boxes provided in the calculator below, press calculate and the total resistance will be provided.
Parallel Resistance Calculator
The parallel resistors calculator provides an easy way to calculate the resistance of two resistors in parallel saving writing everything down and resorting to pen and paper or a calculator of some form.
