How to use the capacitors in series and parallel calculator
Combine capacitors to find total capacitance. Enter capacitor 1, capacitor 2 in the fields above; the parallel, series are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- C1 — Capacitor 1 (µF)
- C2 — Capacitor 2 (µF)
Worked example
With capacitor 1 = 10 µF, capacitor 2 = 22 µF, the calculator gives parallel ≈ 32 µF; series ≈ 6.875 µF.
Frequently asked questions
What is the formula for the capacitors in series and parallel calculation?
Parallel (µF) = C1+C2. Series (µF) = C1 × C2 / (C1+C2). Here C1 is capacitor 1 (µF), C2 is capacitor 2 (µF).
What inputs do I need for the capacitors in series and parallel calculator?
You need capacitor 1 in µF, capacitor 2 in µF. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
