Why do we use Nichrome in an electric heater Class 7?
Nichrome is used for making heating element of electrical appliances. Because nichrome does not oxidize and burn easily at high temperature i.e.it has higher melting and boiling point than metals. Thus it does not melt even when a large amount of heat is produced due to passage of current.
Why does a wire made of Nichrome glow?
The heating element of an electric heater is made of an alloy which has high resistance whereas the cord is made of copper metal which has very very low resistance…now,the heating element of an electric heater made of nichrome glows because it becomes red hot due to the large amount of heat produced on passing …
Why Nichrome wire is used in a heater?
Because of its low cost of manufacture, strength, ductility, resistance to oxidation, stability at high temperatures, and resistance to the flow of electrons, nichrome is widely used in electric heating elements in applications such as hair dryers and heat guns.
How is Nichrome wire used?
Nichrome wire is an alloy made from nickel and chromium. It resists heat and oxidation and serves as a heating element in products such as toasters and hair dryers. Hobbyists use nichrome wire in ceramic sculpture and glassmaking. The wire can also be found in laboratories, construction and specialized electronics.
What household items contain Nichrome wire?
It is also known as heating element wire. Lots of applications uses nichrome wire for the purpose of heating. Some devices that uses heating element wire are heater, toaster, hair dryer, iron, electric thermos, plastic bag sealing machine, etc.
