How do you test nichrome wire? If you have unlabeled nichrome wire, you can determine its type using a wire gauge, Vernier calipers, a good ruler, and an accurate thermometer. The wire gauge can be used to determine its gauge or diameter.
How do you determine the type of nichrome wire?
If you have unlabeled nichrome wire, you can determine its type using a wire gauge or Vernier calipers, a good ruler, an accurate thermometer and a sensitive ohm meter designed to measure very low resistances. Use the wire gauge or calipers to determine its gauge or diameter.
What is nichrome wire used for?
As already mentioned, nichrome wire is used everywhere where heating elements are needed. High resistivity and melting point make it possible to use nichrome as the basis for various heating elements, from a kettle or hairdryer to a muffle furnace. Let's figure out how to calculate the length of a nichrome wire in terms of power and resistance.
Why is it important to use clean nichrome wire for flame test?
It is important to use a clean nichrome wire for each flame test because, if you use a wire that has chemicals from the previous test on it, it may affect the results of the current test. Why platinum wire loops are used for performing the flame test? because platinum wire loops dont impart any color of it own.... NICHROME wire are also used..

You can do some calculations on a resistivity if you know the cross sectional area things like that that's all for that.
What color does nichrome wire burn?
orange tintNichrome wire will produce a slight orange tint in your flame, but it is a popular alternative to Platinum, which is generally cost-prohibitive for most labs.
Can resistance of nichrome be measured?
You can use nichrome as a thermometer by measuring the current with a known voltage across it, that is, by measuring its resistance. You should calibrate it with a known thermometer so that you can translate the resistance into temperature.
What is the resistance of a nichrome wire?

At what temperature does nichrome wire glow?
We can estimate the temperature to be approximately 1700°F at 12 amps.
How do you do a flame test with nichrome wire?
Flame TestsClean a platinum or nichrome (a nickel-chromium alloy) wire by dipping it into concentrated hydrochloric acid and then holding it in a hot Bunsen flame. ... When the wire is clean, moisten it again in the acid and then dip it into a small amount of the solid to be tested so that some sticks to the wire.More items...•
Why must the nichrome wire be cleaned thoroughly between each flame test?
The spectral lines of both (or more) metal ions will be present in the spectrum. This will make identifying the second or new ion very difficult. Cleaning the nichrome wire will limit the spectral lines seen to one element making the identification easier.
Can nichrome be used as fuse wire?
nichrome has a high melting point due to which it is not used as a fuse wire .. if it will be used then the current through circuit will flow and can damage our home appliances....
Does nichrome resistance change with temperature?
This is because nichrome is composed of metals, and the resistivity of metals generally increases with temperature (Bortner). The resistivity is directly proportional to the resistance, so the resistance should increase with the resistivity.
How hot will a nichrome wire get?
The Type A Nichrome Wire has a high temperature range up to 1150°C or 2100°F.
What is the thickness of nichrome wire?
0.05mm to 14mmWidely used in heating equipment, such as electric furnace, hair dryers, electric ovens, etc. Wire thickness range from 0.05mm to 14mm.
How do you measure wires with a multimeter?
By dividing the resistance value for the entire wire by the resistance value for the 1 m length, you can estimate the overall length of the wire (in meters).
How do you find the resistivity of a wire experiment?
0:454:14Measuring the Resistivity of a Wire - PRACTICAL - A Level PhysicsYouTubeStart of suggested clipEnd of suggested clipWe're going to be measuring the length of the wire using a meter ruler to find out the length and toMoreWe're going to be measuring the length of the wire using a meter ruler to find out the length and to find out the area the cross-sectional area that wire you need to measure the diameter.
What is P in R pL a?
The resistivity of a wire is given by R=pL/A. Where p is the resistivity of the material, L is the length of the wire and A is the cross sectional area of the wire.
Does the resistance of nichrome wire change with temperature?
We believe that increasing the temperature of the nichrome wire will cause the measured resistance of the wire to also increase. This is because nichrome is composed of metals, and the resistivity of metals generally increases with temperature (Bortner).
What does the number after nichrome wire mean?
The number that comes after the Nichrome wire type indicates the percentage of nickel in the alloy. For example, "Nichrome 60" has approximately 60% Nickel in its composition. Applications for Nichrome wire include heating elements of hair dryers, heat sealers, and ceramic support in kilns.
What is nichrome wire made of?
Nichrome wire is made of a non-magnetic alloy composed primarily of nickel, chromium, and iron. Nichrome is characterized by its high resistivity and good oxidation resistance. Nichrome wire also has good ductility after use and excellent weldability. The number that comes after the Nichrome wire type indicates the percentage of nickel in the alloy.
What is nichrome 60 used for?
Nichrome 60 is is ideal for use as heating elements in household utilities and in moderate heat, high humidity environments. Applications: Metal sheathed tubular elements used in, for example, hot plates, grills, toaster ovens and storage heaters. The alloy is also used for suspended coils in air heaters in clothes dryers, fan heaters, hand dryers.
Is nichrome 60 a non-magnetic alloy?
Nichrome 60 is less resistant to rust and oxidation as Kanthal, but it has a higher high wet corrosion resistance and is made of a non-magnetic alloy. This means that in acidic environments or areas where a wire is likely to come in contact with a liquid or electrolyte medium, Nichrome 60 wire will resist degradation at a higher level and continue to function for a longer period of time.
Is nichrome 80 good?
Nichrome 80 has very good form stability. This alloy offers superior service life compared to other Nichrome wire types due to the excellent adhesion properties of its surface oxide.
