Question

Which substance is used in the
form of coil in heating eleme
ts?​

Answer 1

Answer:

Nichrome

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

Hope it helps..

Answer 2

• Manufacturers use nichrome to make the heating coils found in common household appliances. Nichrome is combined from nickel and chromium. Wire made from nichrome is especially suited for use in heating coils because of its flexibility. This alloy also has a high melting point.
