Capacitors in Series Calculator FAQ
Answers to common questions about this calculator.
Reciprocals add, so the total is smaller than the smallest.
Charge is equal, so smaller capacitors take more voltage.
1/Ceq = 1/C1 + 1/C2 + 1/C3.
It is an estimate based on the inputs you enter. Check real quotes, labels or official guidance for important decisions.
