Parallel Capacitor Calculator Formula

Understand the math behind the parallel capacitor calculator. Each variable explained with a worked example.

Formulas Used

Total Capacitance

total_cap = c1_uf + c2_uf + c3_uf

Variables

VariableDescriptionDefault
c1_ufCapacitor C1(µF)10
c2_ufCapacitor C2(µF)22
c3_ufCapacitor C3 (0 to skip)(µF)0

How It Works

Parallel Capacitors

C_total = C1 + C2 + C3 + ...

Capacitors in parallel add directly (opposite of resistors). This increases total capacitance.

Worked Example

10 uF and 22 uF in parallel.

c1_uf = 10c2_uf = 22c3_uf = 0
  1. 01C_total = 10 + 22 = 32 uF
