Nichrome is a name for a nickel- chromium resistance wire, a nonmagnetic alloy of nickel and chromium.
Common alloy is 80% nickel and 20% chromium, by weight.
Silvery-grey in colour, corrosion resistant and has a high melting point of 1400 C
(2552 F).
Due to it's high resistivity and resistance to oxidation at high temperatures, it's widely used in heating elements, such as in hair dryers, electric ovens and toasters.
Typically, Nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.
For heating, resistance wire must be stable in air when hot. Nichrome wire forms a protective layer of chromium oxide.

What happens to a nichrome wire when a current flows through it?
When a current flows through a nichrome wire, the wire heats up due to resistance. This increase in temperature causes the wire to glow and emit heat, which is why nichrome wire is often used in heating elements and appliances.
How do you use NiChrome wire?
NiChrome wire is commonly used as a heating element in applications such as electric ovens, toasters, and hair dryers. To use NiChrome wire, you can wrap it around a ceramic or heat-resistant material to create a heating coil. When electricity passes through the wire, it heats up quickly and generates heat.
Should the heating element of an electric iron be made of of iron Silver or nichrome wire?
It should be made of nichrome wire because resistivity of nichrome is high.Its high resistivity causes nichrome to heat up faster, when an electrical current is passed electricity moves through the wires, givingheat to the element.hope it helped
Why is a copper wire in a closed circuit does not get heated but a nichrome does?
this is because copper wire offers no resistance and thus electric current passes through them without producing heat energy whereas in nichrome offers a large resistance and thus the mechanical energy of the drifting electrons changes to heat energy rapidly .
What is nichrome?
Nichrome is a metal alloy containing nickel and chromium, hence the name, usually 80 percent nickel, 20 percent chromium. A nichrome wire loop is a length of wire from this metal with a little loop twisted into one end and a handle attached to the other. You can stick the loop in a flame and not hurt it. These are used in biology to transfer microorganisms to culture media, and in chemistry to do flame tests.
Why does nichrome wire produce and orange light when heated in a flame?
Nichrome wire produces an orange light when heated in a flame due to its high resistance and the temperature it reaches when current flows through it. As the wire heats up, it emits thermal radiation, which includes visible light. The orange color specifically arises from the thermal emission spectrum of the wire, where it radiates light in the orange-red region as it approaches higher temperatures, similar to how heated metals glow. This phenomenon is a result of blackbody radiation, where the color of the emitted light corresponds to the temperature of the material.

Why does nichrome get hot?
Nichrome has a high electrical resistivity.
Why is nichrome used for heating element in a toaster?
A nichrome wire has high resistance and gets heated faster, saving electricity.
What metal or material is used in the rear window defroster?
A High resistance wire, such as NiChrome; the wire heats up when amperage flows through.
How does a light boble work?
A light bulb has a filament wire inside made of nichrome. When electricity is passed through this wire it lights up brightly. If this happens in air the wire burns out and breaks. To stop this, bulbs are filled with a non flammable gas called argon that allows the wire to glow without breaking because there is no oxygen inside the bulb.
Is the definion of a metal easily transmits electricity?
No. Most metals can conduct energy well (energy implying includes electricity and heat). However, some, such as nichrome (an alloy of nickel and chromium) conduct electricity very poorly. Nichrome has a high resistance and therefore, when electricity is chanelled through nichrome wire, resistance in the wire causes it to heat up.
What happens to the wire when heated?
it goes up
Is nichrome wire a good conductor of heat and electricity?
Yes !! It is an alloy of nickel with chromium.Heating ElementsManufacturers use nichrome wire extensively to make heating coils or elements for household and industrial use. You can find it in toasters, hair dryers, heaters and many other appliances.PotteryCeramics enthusiasts use nichrome wire to hold kilns together, and also to hold pottery together while baking. It will not melt or break at these extremely high temperatures.Hot Wire CutterYou can buy or make a cutter that uses a heated nichrome wire for a blade for cutting certain foams and plastics. The hot wire blade cuts cleaner and neater than a saw or knife.Fireworks and Motel RocketsSince nichrome wire heats up rapidly with voltage applied, it makes safe electric igniters for fireworks and model rockets. The operator can safely set off the device from a distance with a battery and a switch.
