The coils of electric toasters or electric irons made of an alloy rather than a pure metal. What is the correct reason for this ? |
The resistivity of an alloy is generally lower than that of its constituent metals. The resistivity of an alloy is generally lower than that of its constituent metals. The resistivity of an alloy is generally same as that of its constituent metals. Alloys are more heat conducive. |
The resistivity of an alloy is generally lower than that of its constituent metals. |
The resistivity of an alloy is generally lower than that of its constituent metals. And they do not oxidize readily at higher temperatures. |
