Quickly calculate the total capacitance of capacitors in series using this calculator. Ideal for electronics design, repair, and learning circuit behavior.
Capacitor in Series Calculator
Capacitors connected in series divide voltage and reduce total capacitance. The total capacitance in series is calculated by taking the reciprocal of the sum of the reciprocals of each capacitor's value. This configuration is commonly used in electronic circuits where a smaller equivalent capacitance is needed or when capacitors need to share a voltage load. The Series Capacitor Calculator instantly computes the total capacitance, making it easy to design accurate and efficient circuits for timing, filtering, or energy storage applications.
Calculate Series Capacitor
A series capacitor calculator helps determine the total capacitance when multiple capacitors are connected end-to-end (in series). In a series connection, the reciprocal of the total capacitance is the sum of the reciprocals of the individual capacitors. This means that the total capacitance in series is always less than the smallest individual capacitor in the group. Series configurations are often used in high-voltage applications to distribute voltage across each capacitor and to fine-tune capacitance levels. This tool is essential for electronics hobbyists, engineers, and students who need accurate and quick results when designing or analyzing circuits. With this calculator, you can input up to any number of capacitor values and instantly get the total series capacitance in farads, microfarads, nanofarads, or picofarads. It simplifies complex calculations and ensures precision in circuit behavior, especially in timing and filtering applications.

| Capacitor (μF) | 4.7 | 10 | 22 |
|---|
| Total Capacitance (μF) | 2.75 |
Calculation:
1/Ctotal = 1/4.7 + 1/10 + 1/22 = 0.2127 + 0.1 + 0.0455 = 0.3582
Ctotal = 1 / 0.3582 ≈ 2.75 μF
What happens when capacitors are connected in series?
The total capacitance decreases and voltage is divided among capacitors.
How do you calculate total capacitance in series?
Use the reciprocal formula: 1/Ct = 1/C1 + 1/C2 + ...
Is total capacitance in series less than the smallest?
Yes, it's always smaller than the smallest capacitor.
Why use capacitors in series?
To achieve a lower capacitance or share high voltage across devices.
What units should I use for capacitors?
Use consistent units (μF, nF, or pF) for all inputs.
Does voltage split equally in series capacitors?
Not always—it depends on each capacitor’s value.
Can electrolytic capacitors be used in series?
Yes, but polarity and voltage ratings must be considered.
What if I mix microfarads and nanofarads?
Convert all to the same unit before calculating.
Is the calculator accurate for any number of capacitors?
Yes, it works for 2 or more capacitors.
Can this tool be used for AC circuits?
Yes, for AC analysis, total capacitance still applies.
