How do capacitors combine in parallel?

They add up: Ctotal = C₁ + C₂ + … — the opposite of resistors.

What is the total of two 10 µF capacitors in series?

5 µF — in series the total is less than the smallest capacitor.

Capacitance adds in parallel and combines as reciprocals in series, the reverse of how resistance behaves.

Capacitors in parallel add up:

C_total = C₁ + C₂ + C₃ + …

Capacitors in series combine as reciprocals:

1 / C_total = 1/C₁ + 1/C₂ + 1/C₃ + …

So the series total is smaller than the smallest capacitor, while the parallel total is the simple sum — exactly the reverse of resistors.
