Parallel Resistor Combination Calculator

See our other Electronics Calculators.

Have you ever been in a situation where you need to create an equivalent resistance using a set of parallel resistors.   It can be a challenge to find the best combination.  This calculator allows you to enter in resistance values that you have available, and to calculate all of the parallel combinations of any two of them instantly. Fill the resistor values in from the top, and leave any unused fields empty.
