Formulae and tables for calculation of inductance of coils of polygonal form
Year: 1922
Single-layer coils wound on formers so that each turn encloses a regular polygon are much used in radio measurements since such coils are easy to construct, have small self-capacity, and the wire is only supported by solid dielectric at the vertices of the polygon, thus reducing dielectric losses to a minimum. The paper provides formulae from which the inductance of coils wound on triangular, square, hexagonal or octagonal formers can be calculated. It is shown that the polygonal coil has an inductance which is nearly the same as that of a circular coil of equal number of turns and axial length, if the circular and the polygonal forms enclose the same area. The results are presented in such a way that the radius of the circular coil%
