Question

Why are coils of electric toasters and electric irons made of an alloy rather than a pure metal?

Answer 1

Answer:

The melting point of an alloy is much higher than a pure metal because of its high resistivity. At high temperatures, alloys do not melt readily. Therefore, alloys are used in heating appliances such as electric toasters and electric irons.

Answer 2

$\huge\underline \mathfrak\red{Answer}$

Coils of electric toasters and electric irons made of an alloy rather than a pure metal due to the following reasons:

• The resistivity of an alloy is higher than the pure metal.
• Alloy does not melt readily and get deformed.
• Alloys have a low-temperature coefficient of resistance.
