A deterministic approach based on the variational principle is employed to derive the relationships among the bulk cable current and its individual wire currents. These relationships can be utilized to develop as well as to verify pin specifications of a Line Replaceable Unit LRU via direct-drive tests, either onboard an aircraft or in a laboratory. A set of canonical problems involving 2-wire cable over a ground plane is studied in detail to check the derived relationships and to analyze common- and differential-mode current distributions under various conditions. New experiments are suggested to verify as well as to improve the results reported herein. Keywords include Cable bundle, Wire currents, Variational technique, Electromagnetic pulse EMP, Common- and differential-modes, Direct-drive testing, and Line replaceable unit LRU.
