Joule Heating The flow of current through a resistance is accompanied by heat. Joule experimentally determined that the energy dissipated during current f flow in a conductor is,

Q= I 2 Rtwhere,–––– Q= Energy (heat) generated I= current flow cu e t o R= thermal resistance t= time of current flow

Time rate of heat generation

& Q= I 2R(Entered as power in Icepak models)

Joule heating can be specified for three dimensional solid blocks and plates
