Capacitors in series calculator

Calculate series capacitance with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use series capacitance to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Series capacitance (µF)

Take the reciprocal of each capacitance in a, add the reciprocals, then take the reciprocal of the sum.

Symbols and units
a
Capacitances (µF)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Ideal capacitors in series add reciprocal capacitances. Lists support up to 1,000 finite values.
