Question

why are coils of electric toaster and electric iron made up of an alloy rather than a pure metal​

Answer 1

hyy mate ✌️

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.

hope it will help you ❣️

Answer 2

This is because the resistivity of an alloy is more than the resistivity of a pure metal and hence more heat is produced in an alloy than a pure metal due to the flow of current . Moreover, alloy does not burn (or oxidise ) easily even at higher temperature .
