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