✦ Synopsis

Energy conversion takes place either in generalized capacitor or generalized resistor networks, that is, C-and R-$elds in the sense of Paynterian bondgraphs. Entropy is interpreted aa a kind of thermal charge. An electrical example is th,e difference of conduction and convection associated with mass few. The generation of entropy in irreversible processes is represented by RS-fields as extension of the simple generalized resistors or R-elements. Thermoelectric power conversion is described by combined RS-fields, and Onsager's symmetry conditions for such jielda are derived from the second law of thermodynamics.
