Exact inductance equations for rectangular conductors with applications to more complicated geometries

Exact eq uations a re given for t he calculation of t he self-inductance of rcctangular conductors a nd of t he lIlutual inducta nce between combinations of parallel fil a mcnts, thin tapcs and rectangular conductors. A general procedure is also given for calculating the sclfinductance of complicated geometri es by dividing the gcometry into simple elcm ents whose inductances can be calculated. This general proccdure is valid for conductors having nonuniform, as well as uniform current dcnsities. ' R adio Standards Ellginecring Division, NBS Boulder Laboratories, Boulder, Colo.
