Electrical relationship
Formula
C_total = C1 + C2 + C3= 79
Note
This is a simplified model: it applies the textbook relationship to the numbers you entered and assumes ideal components, steady-state sinusoidal conditions, balanced loads and copper resistivity of 0.0172 Ω·mm²/m at 20 °C. It ignores component tolerances, temperature drift, skin effect, harmonics, inrush, transformer and battery losses, and it is not a substitute for the wiring code that applies where you are. Have any installation sized and verified by a licensed electrician or engineer.

How do I calculate total capacitance for capacitors in parallel?+
Simply add the values: C_total = C1 + C2 + C3 + ... Parallel capacitance adds directly, unlike parallel resistance, because each capacitor contributes its own plate area to store charge.
Why does capacitance add in parallel instead of using a reciprocal formula?+
Putting capacitors in parallel effectively increases the total plate area available to store charge at the same voltage, so their capacitances simply combine. This is the opposite behavior of resistors, which add directly in series instead.
Do parallel capacitors all charge to the same voltage?+
Yes, since they share the same two connection points, every capacitor in the parallel group reaches the same voltage. The total stored charge is just the sum of each capacitor's individual charge at that voltage.
Is there a limit to how much capacitance I can combine in parallel?+
Practically, no — you can keep adding capacitors and the total keeps growing. The real-world limits are physical size, cost, and the voltage rating of the weakest capacitor in the group.
Why would someone use several capacitors in parallel instead of one big one?+
Combining several smaller capacitors is often cheaper, more compact, and easier to source than a single equivalent large one, and it can also reduce equivalent series resistance for high-current applications like power supply filtering.
