Formula

1/C_total = 1/C₁ + 1/C₂ + 1/C₃ + ..., where each C is the capacitance of an individual capacitor in farads.

Frequently Asked Questions

How do capacitors add in series?
Capacitors in series add reciprocally: 1/C_total = 1/C₁ + 1/C₂ + 1/C₃ + ... The total capacitance is always less than the smallest individual capacitance.
Why use capacitors in series?
Connecting capacitors in series increases the total voltage rating (the voltages add) while decreasing the total capacitance. This is useful when a higher voltage rating is needed than any single capacitor can provide.
