Calculation Formula

Resistance (Ω): R = ρ / (π * (d/2)^2 * L)

Inductance (nH/m): L = (μ₀ * μᵣ * 2 * ln(S/d)) / (4π)

Where:
R = Resistance (Ω)
ρ = Resistivity (Ω·m)
d = Wire Diameter (m)
L = Conductor Length (m)
μ₀ = Permeability of free space (4π × 10⁻⁷ H/m)
μᵣ = Relative permeability of the material
S = Wire Spacing (m)

Working Principle

The resistance of a twin wire line is calculated based on the resistivity of the conductor material, the diameter of the wire, and the length of the conductor. The inductance is calculated based on the wire spacing, wire diameter, and the permeability of the material.

The formulas used are:

Resistance (Ω): R = ρ / (π * (d/2)^2 * L)

Inductance (nH/m): L = (μ₀ * μᵣ * 2 * ln(S/d)) / (4π)

Where:

  • R = Resistance (Ω)
  • ρ = Resistivity (Ω·m)
  • d = Wire Diameter (m)
  • L = Conductor Length (m)
  • μ₀ = Permeability of free space (4π × 10⁻⁷ H/m)
  • μᵣ = Relative permeability of the material
  • S = Wire Spacing (m)
