Heat transfer aspects of electric heating

THIS PAPER is a discussion of the principles of steady-state heat transfer as they apply to the field of electric heating and, as such, no solutions are derived, but rather the governing differential equations are presented and references containing the solutions for various boundary conditions are cited. In most of the references given, the work was concerned with the temperature distribution in electric coils or other electric apparatus wherein the generation of heat was an unwanted phenomenon and not as is considered here, the prime function of the device. However, since these are the solutions to basic differential equations, they are directly applicable to any other body for which the basic equation and the boundary conditions hold.
