Question

Should the heating element of an electric iron be made of iron ,silver or nichrome wire

Answer 1

Answer:

Nichrome: Most resistance wire 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.
