Question

Answer 1

because the resistance is more in some metals like nicrome

Answer 2

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.I think u have understood
