What is Resistance Heating? When the heat is produced by passing electric current through the resistance of a conductor, it is called electric resistance heating (ERH). This method of electric heating is based on the principle of I2R loss. If ‘P’ is the electric power developed in the heating circuit and ‘t’ is the time in seconds.

Electrical resistance heating (ERH) is an intensive in situ environmental remediation method that uses the flow of alternating current electricity to heat soil and groundwater and evaporate contaminants. Electric current is passed through a targeted soil volume between subsurface electrode elements.

Joule heating, also referred to as resistive heating, or ohmic heating, is a phenomenon where thermal energy is produced by an electrical current. Heat generation occurs due to frictional forces that retard the electrical current from freely flowing through a conductor to a lower potential, which is commonly known as electrical resistance.

Heater resistors are used whenever an electronic device needs to generate heat for some reason. They are designed as a special type of power resistor to provide a reliable and controllable source of heat.

Resistive heating is the process of converting electricity into heat energy. Fixed wattage heaters are typically manufactured with resistive wires or etched circuits.
