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