What it calculates
The “Parallel Resistance” calculator computes Resistance in Ω from 3 parameters: r₁ (Ω), r₂ (Ω), r₃ (Ω).
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters R₁ = 100 Ω, R₂ = 220 Ω, R₃ = 0 Ω the result is 68.75 Ω (1/R = 1/R₁ + 1/R₂ + 1/R₃).
How to use
- Enter r₁, r₂ and r₃ — each field above is adjustable with a slider.
- Resistance (Ω) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.
- Copy the result or bookmark this calculator.
