Series and parallel components
Combine up to twelve resistors or capacitors and compare series and parallel equivalents. Change the inputs to update the chart or diagram.
Your inputs
Example values are editable. Use your measurements and product specifications. Results update as you edit.
Calculations run in your browser. Inputs are not saved or sent to analytics.
How it works
- Rseries = Σ; 1/Rparallel = Σ(1/)
- Cparallel = Σ; 1/Cseries = Σ(1/)

Assumptions and limitations
Enter all resistor values in ohms or all capacitor values in microfarads. Only a single series or parallel group is modeled; values must be positive. Components are ideal, without tolerance, leakage, ESR or voltage-rating calculations. Two 1,000 Ω resistors give 2,000 Ω in series and 500 Ω in parallel.
