Frequency Characteristics of Inductively Coupled Two Circuits

Abstract

The vector ratios of two quantities among voltages, currents and charges of inductively coupled two circuits are calculated, and their properties under variable freguencies are investigated by tracing their vector loci.
Generally, the loci commonly used in the alternating current theory, are almost circles The frequency characteristics of inductively coupled two circuits, however, are seldom represented by simple circles or straight lines, but almost always by s ch loci that are guided by parabolas or their inversions or besides them guided by circles or straight lines.
General forms of such loci are described in the text for each of twelve i nportant ratios, while their details are shown in the appendices with curves and tables.
