Computations of temperature distributions in solids of simple shape with internal heat generation produced by the passage of an electrical current through the solid become somewhat complicated when the temperature dependence of electrical conductivity must be taken into account. Ana lytical solutions are presented for a special case of temperature dependence which form the bases for developing simple criteria for determining when temperature dependence needs to be taken into account. It is shown that for nearly all metals temperature changes in the order of hundreds of degrees are required before significant effects of electrical-conductivity temperature dependence are realized. Also presented are convenient numerical procedures especially suitable for hand computation of temperature distributions when both electrical and thermal conductivity temperature dependences must be considered. The flat slab, cylindrical rod, and hollow cylinder are the shapes considered. (auth)
