A Study of the Resistivity Method Using a Resistance Network Analyzer

Abstract

In the engineering field, many problems arise which are solved by Laplace's equation. These problems such as gravitation, electrostatics, magnetics, heat transfer and fluid mechanics, can be solved approximately by use of a resistance network analyzer. In the present paper, the authors discuss the resistivity method with such an analyzer which has been applied to the investigation of electrical prospecting by the authors and their assistants since 1954. It is shown that the resistivity curves obtained with this analyzer agree with the curves calculated theoretically, so that the authors are sure that this method of determining the resistances of boundaries is satisfactory, and that this analyzer will be an indispensable instrument in the solution of resistivity problems that can not be solved theoretically.
