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

Text Solution

Verified by Experts

To produce more heat, the high melting point of conductors is necessary. The alloys of metal have higher melting points than pure metals. Thus, to retain more heat alloy is used rather than pure metal in electrical heating devices, such as btead- toaster, electric iron,.etc.
