What is Electric Resistance Heating?

Electric resistance heating is a heating system that uses electrical energy to produce heat. It works by passing an electric current through a material with high electrical resistance, such as a metal wire or an alloy, which generates heat. The heat generated can be used for various applications, such as heating, drying, and melting.

How Does Electric Resistance Heating Work?

Electric resistance heating works by converting electrical energy into heat energy through the resistance of a material to electric current. The process is simple: when an electric current is passed through a material with high electrical resistance, the material resists the flow of electricity, which generates heat.

The amount of heat generated by electric resistance heating depends on several factors, such as the current flowing through the material, the resistance of the material, and the time the current flows through the material. The temperature of the material also affects the amount of heat generated.
