Joule heating affects the whole electric conductor, unlike the Peltier effect which transfers heat from one electrical junction to another. Joule-heating or resistive-heating is used in many devices and industrial processes. The part that converts electricity into heat is called a heating element. Among the applications are:
Electric heating devices can be built in any required size and can be located anywhere within a plant. Electric heating processes are generally clean, quiet, and do not emit much byproduct heat to the surroundings. Electrical heating equipment has a high speed of response, lending it to rapid-cycling mass-production equipment.
A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule heating.
For example, space heaters use heating elements much hotter than the room being heated. In these applications, a thermostat may be better able to sense and control the temperature of the item being heated. Nevertheless, a self-regulating heating element may still be used to keep the heating element from damaging itself or other parts of the heater.
Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
Heating films are a method of electric resistance heating, providing relatively low temperatures (compared to many conventional heating systems) over large areas. Heating films can be directly installed to provide underfloor heating , wall radiant heating and ceiling radiant heating.

The heating caused by the induced current is called ohmic (or resistive) heating; it is the same kind of heating that occurs in an electric light bulb or in an electric heater. The heat generated depends on the resistance of the plasma and the amount of electric current running through it.
