Comments Regarding my Electric Current Flow Design and Analysis Work:
: The flow of electric current is the very basis of all electronic and much electrophysical phenomena. I have found finite element analysis (FEA) methods to be very helpful in understanding various electric current flow scenarios in simple and not so simple situations. This includes numerical experiments with current flow and power dissipation in planar and three dimensional conductors and conducting regions with complex geometry.; I have modeled current flow in various electrolytic cells of the kind used in fuel cells and electrochemical experiments. These models were helpful in determining cell and electrode geometries and locating reference electrodes in these cells.; I have produced spread sheet models for complicated current conductor geometries involving arrays of tubular conductors embedded in weakly conducting plates.
