Abstract

The electro-thermal analogy and the interaction aspects are investigated. Their criteria are defined. The electrical and the thermal conductance invariants are drawn out as generalized resistances. The interaction of the electrical conductance and the thermal electronic one is studied. The capability of the application of the analogy and the interaction laws to the contact conductance is considered. The calculation expressions for the generalized constriction resistances actual in space power plants are proposed. Their limits are analyzed.
