INTRODUCTION
Electrothermal processes can be divided into two broad categories:
indirect heating, where the transmission of energy from the source to the receiver (the body to be heated) obeys the usual laws of thermics;
direct heating, where the receiver, through which an electric current flows, is itself the source of heat release, with subsequent heat exchanges taking place according to the laws of classical thermics.
Table 1 lists the various electrothermal technologies that fall into these two families.
