Question

Nichrome is usedtomakethe element of electric heater .why?

Answer 1

Nichrome: Most heating elements use nichrome 80/20 (80% nickel, 20% chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time.

Answer 2

When an electric current is passed through a high resistance wire, like nichrome wire, the resistance wire becomes hot and produces heat. So, nichrome is used to make the element of electric heater.
