Why is nichrome used for heating elements 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.

Why nichrome is used as heating element give two reasons?

Nichrome is used to make the heating elements of electrical appliances because it has a high resistance and a high melting point.

Why is nichrome used as a heating element Class 7?

Nichrome doesn’t burn easily at high temperatures as it has higher melting and boiling point than metals.

Which wire is used as heating element of heater?

Nichrome: Most resistance wire heating elements usually use nichrome 80/20 (80\% Nickel, 20\% Chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time.

Why are you use Nichrome wire in electric iron or electric heater?

Nichrome wire should be used as the heating element in an electric iron. The reasons are mentioned below: High resistivity thus ensuring the wires to heat up faster. High specific heat which provide enough heat to the element.

Why Nichrome wire is used in Ohm’s law because?

Because nichrome wire has higher resistance and better electrical conductivity.

Why is Nichrome used for electrical appliances?

Nichrome is used for the making of heating elements of electrical appliances because, Nichrome has high resistivity. Nichrome does not oxidize when exposed to air.

Is Nichrome used for making heater rods?

Answer: 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. Moreover, It has higher resisistivity and consequently a higher resistance.

Why is nichrome used for heating elements of heaters and toasters Class 7?

Why nichrome wire is used in Ohm’s law because?

Why Nichrome is used in electric iron?

It has a high melting point such that it can sustain high temperatures. Nichrome is an ideal material for heating elements for an electric iron also because the oxide layer formed helps to protect the inner material from oxidizing which doesn’t let internal wires burn.
