TIME-AVERAGED TEMPERATURE DISTRIBUTION IN A CYLINDRICAL RESISTOR WITHALTERNATING-CURRENT

The non-uniform heat generation in a cylindrical resistor crossed by a n alternating electric current is considered. The time averaged and di mensionless temperature distribution in the resistor is analytically e valuated. Two dimensionless functions are reported in tables which all ow one to determine the time averaged temperature field for arbitraril y chosen values of the physical properties and of the radius of the re sistor, of the electric current frequency, of the Biot number and of e ither the power generated per unit length or the effective electric cu rrent.
