sorry I didn't know about this question
Answer:
False
Explanation:
Correct statement = A coil made up of an alloy of Nichrome is used in electric iron as an Heating Element.
The reason being that Nichrome has very hight resistance.
And we know that,
Resistance is directly proportional to Heat.
So more is the resistance, more is the heat.
This helps in efficient working of Iron.
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. Material beneath this layer will not oxidize, preventing the wire from breaking or burning out.
Hence, nichrome is used as heating elements.
