Single-conductor resistance
Enter physical properties to estimate a single conductor’s resistance.
Method and boundaries
R₂₀ = ρ₂₀ × L / A; Rₜ = R₂₀ × [1 + α(T − 20 °C)]. Cross-sectional area is entered in mm² and converted internally to m².
Single conductor only; this is not an outgoing-and-return loop. The material label does not select values. Ampacity, installation method, material limits and code compliance are not evaluated.
Method and boundaries
R₂₀ = ρ₂₀ × L / A; Rₜ = R₂₀ × [1 + α(T − 20 °C)]. Enter cross-sectional area in mm²; the model converts it to m².
The material name is descriptive only and never selects hidden constants. This is a single conductor, not a return loop. Ampacity, installation method, material ratings and code compliance are not evaluated. SRC-001 · model 1.0.0 · user-input-v1.
