THESE FORMULAS ARE APPROXIMATIONS!
They should not be used when a high degree of accuracy is required.
The approximate formulas are provided along with restrictions on the relative size of the various parameters.
All the units are in SI (Iternational System):
- [m] = meter
- [s] = second
- [H] = Henry
- [F] = Farad
