In all cases, the current is assumed to flow in the outer
surface of the conductors.
The approximate formulas used to calculate the inductance are
provided along with restrictions on the relative size of the
various parameters.
All the units are in SI (Iternational System):
- [m] = meter
- [H] = Henry
