Question

Why are the conductors of electric heating devices, such as bread-toasters and electric irons, made of an alloy rather than a pure metal? (Explain)

Answer 1

❤️Conductor of electric heating devices such as toaster or electric iron is made of an alloy rather than pure metal :-

1⃣ Because if electric heating devices are made up of pure metal then the metal melt easily when heat is increase and pure metal get corrode easily.

2⃣ Alloy does not corrode easily and its melting point is high, 

Answer 2

Dear Student,

◆ Explanation -

• Electric iron and bread-toaster work on the principal of heat production by electric work.
• Alloys have more resistivity leading to high resistance which in turn produces more heat.
• Also melting point of alloys is more than that for metals.
• Therefore, alloys are preferred to create electric heating devices instead of metals.

Thanks dear. Hope this helps..
