Question

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

Answer 1

Answer:

Explanation:because :

#they are less costly

# Have a higher resistance

#having a higher conductivity

than pure metals, they

produce higher amount of

heat

Answer 2

Explanation:

The resistivity of an alloy is higher than the pure metal. Moreover, at high temperatures, the alloys do not melt readily. Hence, the coils of heating appliances such as electric toasters and electric irons are made of an alloy rather than a pure metal.
