Payment options Parallel Resistance Formula Rtotal = (1/R1 + 1/R2 + 1/R3 +…. + 1/Rn)-1
Example Calculation
Consider four subwoofers in parallel with the following resistance values: 1 Ω, 6 Ω, 15 Ω and 100 Ω. The total effective resistance is 0.80 Ω.

If you have two subwoofers – one having large and the other small resistance values in parallel, the effective resistance is closer to the smaller value. Take for instance 1 Ω and 100 Ω in parallel. The effective resistance is 0.99 ≈ 1 Ω.
Series connection
Enter the resistance values separated by commas.
