Why does nichrome get hot?
Nichrome has a high electrical resistivity.
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 components make up a heating element?
Usually Nichrome, as it has very high resistance and does not oxidize in its usual temperature range.
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 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.
What alloy is nichrome made of?
nichrome alloy is made by mixing up of the metals nickel and chromium.
Will a nichrome wire light up when heated?
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. Kimber :)
How does generate electricity?
The resistance of electrons flowing through conductors cause heat. When alloy metals such as Tungsten, Nichrome, Geman silver, brass or bronze are used they heat up quickly. Generally the thicker the wire the less resistance therefore less heat.

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 the nichrome wire get heated first than copper wire?
Because Copper is an excellent conductor of electricity it would take too much copper wire to make an element having sufficient resistance to fit into the small space provided in any normally-sized electric heater. For that reason heating elements must be made from metals which have a much higher electrical resistance than Copper. Special alloys of metals such as Iron, Cobalt, Nickel, Zinc and Manganese have been invented for this purpose.
