Experimental researches on skin effect in conductors

1. Discussion on the paper of Dr. J. A. Fleming, “On Some Effects of Alternating-Current Flow in Circuits having Capacity and Self Induction,” Journal Institution of Electrical Engineers, London, Vol. XX, May 1891, p. 471. The results are given of about one hundred series of tests, each covering a range in frequency up to about 5000 cycles per second, on the impedance of long loops of parallel conductors of different metals, sizes, and cross-sectional forms. The measuring apparatus is detailed. The theory of the skin effect in solid rods and in indefinitely wide flat strips is appended in a new and simplified form.
