Formula and worked example
For ideal capacitors in series, 1/Ceq = Σ(1/Ci). With 10 µF and 20 µF, Ceq = 6.6666667 µF. Values are normalized to farads before calculation; displayed engineering units are selected separately.
Limits and safety
These calculations use ideal component models. Verify component ratings and equipment documentation before practical use. These formulas do not determine whether a circuit or installation is safe or code compliant.
