AC Resistance and Reactance of Isolated Rectangular Conductors

The recently proposed normal mode theory of current flow in straight, long conductors is applied to nonmagnetic, isolated, rectangular bars of various side ratios. Sufficient modal parameters have been computed to permit families of conductor resistance ratio and inductance variation curves to be given. These curves may be used to estimate the alternating current parameters of nearly any rectangular conductor with an accuracy of about 0.5 percent for the resistance, and about one nanohenry per meter for inductance.
