Answer 2

Answer:

Hii,

Explanation:

$\large{\underline{\boxed{Answer:-}}$

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.
• At high temperatures, the alloys do not oxidize.
• Alloy does not melt readily and get deformed.
• Alloys have a low-temperature coefficient of resistance

Hope it will help you....
