Series and Parallel Resistance Calculator
Calculate equivalent resistance for ideal series and parallel resistor networks with visible formulas and boundaries.
Calculator
Result
Enter one or more resistances and choose Calculate.
Method and boundaries
Series resistance is the sum of each resistor. Parallel resistance uses the reciprocal sum. This calculator covers one ideal topology at a time; mixed networks, wiring resistance and code compliance are not evaluated.
