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



Question 4:
Why are coils of electric toasters and electric irons made of an alloy rather than a pure metal?
Solution:
Coils of electric toasters and electric irons made of an alloy rather than a pure metal because the resistivity of an alloy is higher than the pure metal. Also at high temperatures, the alloys do not melt easily.
