Use this free online tool to calculate total capacitance for capacitors connected in series or parallel. Supports unit conversion (μF, nF, pF) and provides step-by-step examples.
Capacitance in Series
✅ Method:
When capacitors are connected in series, the total capacitance decreases. It’s like increasing the gap between plates — overall capacity to store charge drops.
📘 Formula:
1/Ctotal=1/C1+1/C2+1/C3+…
To find total capacitance, take the reciprocal of the sum of reciprocals.
Example:
-
C1=10 μF, C2=20 μF
1/Ctotal=1/10+1/20=3/20⇒Ctotal=20/3≈6.67 μF
Capacitance in Parallel
✅ Method:
When capacitors are connected in parallel, the total capacitance increases. It’s like making the plate area bigger — more charge can be stored.
📘 Formula:
Ctotal=C1+C2+C3+…
Just add all capacitance values directly.
Example:
-
Example:
Calculate total capacitance for capacitors of 10μF, 20μF, and 30μF connected in parallel.
Solution:
Ctotal = 10μF + 20μF + 30μF = 60μF
