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.
Common searches this calculator answers include “equivalent capacitance”, “add capacitors”, “calculate capacitors in series and parallel”, “find parallel”, “find series”.
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.
Tips for accurate results
- Parallel capacitances add directly; series capacitances combine like parallel resistors.
- Keep all values in the same unit, such as µF, before combining.
- The series total is always smaller than the smallest capacitor in the chain.
Common mistakes
- Adding series capacitors directly, which overstates the total capacitance.
- Mixing µF and nF values without converting.
- Assuming the voltage rating of the combination equals the rating of one capacitor; series strings share the voltage.
Frequently asked questions
What is the capacitors in series and parallel calculator used for?
Combine capacitors to find total capacitance. It helps with questions such as “equivalent capacitance”, “add capacitors”, “calculate capacitors in series and parallel”.
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 the capacitors in series and parallel 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 capacitors in series and parallel 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.
