Capacitor Calculator FAQ
Everything you need to know about calculating capacitance, circuit configurations, and electronics fundamentals.
To calculate the total capacitance of capacitors in parallel, simply add their individual capacitance values together: C_total = C1 + C2 + C3 + …
For capacitors in series, the reciprocal of the total capacitance is the sum of the reciprocals of the individual capacitances: 1/C_total = 1/C1 + 1/C2 + 1/C3 + …
Connecting capacitors in series effectively increases the overall distance between the outermost plates, which reduces the total capacitance. The total capacitance will always be less than the value of the smallest individual capacitor in the series.
Yes, the calculator automatically converts all inputs (pF, nF, µF, mF, F) into a common base unit (Farads) before performing the calculation, allowing you to mix and match units seamlessly.
