Capacitors in Parallel and Series Calculator

Capacitors combine in the opposite way to resistors. Wire them in parallel and the capacitances add up, giving a larger total, while wiring them in series makes the total smaller using a reciprocal formula. This calculator does both. Enter your capacitor values in microfarads, pick series or parallel, and it returns the equivalent capacitance. Parallel capacitors are common when you need more bulk storage or filtering than a single part provides, and series capacitors let you raise the working voltage or reach an odd value you cannot buy. The reciprocal series result means two equal capacitors in series always give exactly half the value, just like two equal resistors in parallel. List as many capacitors as you like, separated by commas or spaces. Everything runs locally in your browser, so it is instant and completely private.
