How to use this tool

  1. Enter capacitor c₁, capacitor cā‚‚, capacitor cā‚ƒ (optional) and capacitor cā‚„ (optional) in the fields above.
  2. Results update instantly as you type — or click Calculate.
  3. Read your series capacitance and the full breakdown beneath it.

Two different capacitors in series always produce a value lower than the smaller one — here about 6.67 nF from a 10/20 nF pair.

Frequently asked questions

Why does series wiring reduce capacitance?
Each capacitor in series adds to the effective gap between plates, reducing the ability to store charge. It is the mirror image of parallel resistors.
When would I wire capacitors in series?
To increase the voltage rating of a capacitor bank, or to achieve a smaller capacitance than any available single component.
