Why are conductors of electric heating devices such as toasters or electric iron is made of an alloy rather than pure metal
Answers
Answer:
Purpose of heating devices is to generate high temperatures for cooking or warming applications. It is obvious that we would like to use such a material that can withstand high temperature without getting deformed. There are lots of heating devices i.e. electric heater, electric blower, toaster, immersible rod. Alloy is used in all of them. It has been found that alloys have higher melting point due to high resistance. Hence alloy is used in heating devices.
Answer:
Explanation:
The resistivity of an alloy is higher than the pure metal.Moreover, at high temperatures, the alloy do not melt reidly. Hence the coils of heating appliances such as electric toastres and electric irons are made of an alloy rather than a pure metal.Resistivity of mercury is more than that of iron.....
