Question

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

Advertisements

Solution

The coils of the heating elements of electric irons and electric toasters are made of alloys like nichrome rather than a pure metal because alloys have a high resistance and a high melting point.
