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.
How to use Capacitors in Parallel and Series Calculator
- Choose series or parallel for your capacitor arrangement.
- Enter each capacitor value, keeping all in the same unit.
- Read the total capacitance using the add rule for parallel or the reciprocal rule for series.
- Switch the mode to compare both arrangements.
Frequently asked questions
How does capacitance combine differently in series and parallel?
Parallel capacitors add directly, while series capacitors combine by the reciprocal rule, so the tool applies the correct method based on your selection.
Why is series capacitance smaller than the smallest capacitor?
In series the charge is shared across each capacitor, reducing the effective capacitance below any single value, the opposite of how resistors behave.
What units should I enter?
Enter all capacitors in the same unit, such as microfarads or nanofarads, and the total is returned in that same unit.
What is 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.
