Series Capacitor Calculator
Calculate the total capacity based on the capacity of each series connection
A Series Capacitor Calculator is a tool used to calculate the total capacitance of capacitors connected in series in an electrical circuit.
What is it?
When multiple capacitors are connected in series, the total capacitance (C_total) is less than the capacitance of any individual capacitor. The Series Capacitor Calculator helps you determine this combined capacitance.
Why is it important?
Capacitors in series are common in electrical circuits for controlling voltage, storing energy, and managing frequencies. Knowing the total capacitance allows you to design circuits properly and ensure components behave as expected.
How does it work?
The formula for calculating the total capacitance Ctotal of capacitors in series is:

Where:
- C1,C2,C3,…are the capacitances of the individual capacitors in the series.
You simply enter the capacitance values of the individual capacitors, and the calculator will compute the total capacitance.
When is it used?
You would use this calculator when designing circuits with capacitors connected in series, such as in:
- Power supplies
- Signal filtering applications
- Timing circuits
- Voltage regulation systems
