100pF and 100pF in parallel = 200pF
Worked answer for a 100pF capacitor and a 100pF capacitor wired in parallel.
Equivalent capacitance 200pF 100pF ∥ 100pF in parallel
| Capacitor 1 (C₁) | 100pF |
| Capacitor 2 (C₂) | 100pF |
| Connection | parallel |
| Formula | C = C₁ + C₂ |
| Equivalent capacitance | 200pF |
In parallel, capacitors ADD up — the opposite of resistors in parallel.
