Formula
The Capacitors in Series Calculator uses the formula:
Total capacitance = 1 ÷ (1 ÷ Capacitor 1 + 1 ÷ Capacitor 2)
Worked example
For example, with capacitor 1 of 10 µF and capacitor 2 of 10 µF, the total capacitance is 5.0000.
| Capacitor 1 | 10 µF |
|---|---|
| Capacitor 2 | 10 µF |
| Total capacitance | 5.0000 |

Frequently asked questions
The reciprocal of the total equals the sum of the reciprocals: 1/C = 1/C1 + 1/C2. Two 10 µF capacitors in series give 5 µF.
In series the charge is shared across capacitors, so the combined capacitance is always less than the smallest one.
Capacitors in series behave like resistors in parallel, and vice versa, because of how charge and voltage divide.
Series capacitors share the applied voltage, which can raise the overall voltage the combination withstands.
The Capacitors in Series Calculator uses the formula: Total capacitance = 1 ÷ (1 ÷ Capacitor 1 + 1 ÷ Capacitor 2). For example, with capacitor 1 of 10 µF and capacitor 2 of 10 µF, the total capacitance is 5.0000.
Enter the capacitor 1. Enter the capacitor 2. Read off your total capacitance — the calculator updates automatically, with no button to press.
