Expand description
Provides analytical formulas for computing the electrical resistance of homogeneous conductors with idealized geometries, including rectangular prisms (cuboids), cylindrical segments (axial, radial, and tangential), and hollow spheres.
All functions assume:
- Steady-state conduction (no displacement current),
- Homogeneous and isotropic material properties,
- Idealized geometric shapes,
- Current distributions consistent with the analytical solutions.
The parameter fraction, where present, represents the geometric fraction
of the full body (e.g. 1.0 = full geometry, 0.5 = half).
These utilities are primarily intended for use in
Wire::resistance.
