Parallel Capacitance Calculator Formula
Understand the math behind the parallel capacitance calculator. Each variable explained with a worked example.
Formulas Used
Total Capacitance
total_capacitance = c1 + c2 + c3Variables
| Variable | Description | Default |
|---|---|---|
c1 | Capacitor 1(μF) | 100 |
c2 | Capacitor 2(μF) | 220 |
c3 | Capacitor 3 (0 if unused)(μF) | 0 |
How It Works
Parallel Capacitance
Capacitors in parallel add directly, combining their charge storage ability.
Formula
C_total = C1 + C2 + C3 + ...
Each capacitor sees the same voltage, and the total stored charge is the sum of individual charges.
Worked Example
Two capacitors in parallel: 100 μF and 220 μF.
c1 = 100c2 = 220c3 = 0
- 01C_total = C1 + C2
- 02C_total = 100 + 220
- 03C_total = 320 μF
Frequently Asked Questions
Why does parallel capacitance increase?
Each parallel capacitor provides additional area for charge storage. More area at the same voltage means more total capacitance.
Do parallel capacitors share the same voltage?
Yes, all components in parallel have the same voltage across them.
Is this the opposite of parallel resistance?
Yes. Capacitors add directly in parallel (like resistors in series), and add reciprocally in series (like resistors in parallel).
