Resistance wire is a type of wire made from a material with high electrical resistance, such as nichrome.
It is commonly used in heating elements, such as those found in toasters, ovens, and hair dryers, as well as in industrial applications like furnace heating and thermocouples.
The high resistance of the wire allows it to generate heat when an electric current is passed through it, making it an effective heating element.
