Variables

VariableDescriptionDefault
c1Capacitor 1(μF)100
c2Capacitor 2(μF)220
c3Capacitor 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
  1. 01C_total = C1 + C2
  2. 02C_total = 100 + 220
  3. 03C_total = 320 μF
