Nichrome Wire (100gm)
Product Code : SCL-EAE-11252
Quick answer: Nichrome Wire (100 g) is a nickel-chromium resistance wire with a high resistivity that resists oxidation when hot. In physics practicals it is used to show the heating effect of electric current, to study resistance against length, and to wind resistance coils and small heating elements. Lab Exports manufactures it in Delhi for schools, colleges and universities.

Uses
Nichrome is a nickel-chromium alloy with a much higher resistivity than copper and a surface that resists oxidation even when red hot. Because a short length has a useful resistance and survives high temperatures, it is the standard wire for heating elements and for demonstrating the heating effect of current, H = I^2 R t.
- Confirm the gauge and the safe current for the practical.
- Cut the required length and fix it between heat-resistant terminals.
- Connect it to a current-limited low-voltage supply with an ammeter in series.
- Raise the current gradually and observe the wire warming, or record V and I to find its resistance.
- Switch off and let the wire cool before touching it.
Students can compare nichrome with copper or constantan of the same length and gauge to see how the material affects resistance, and relate the heating they observe to electric heaters, irons and toasters.

Frequently asked questions
What is nichrome wire used for in the lab?
It is used to demonstrate the heating effect of electric current, to compare the resistance of different materials, and to make resistance coils and small heating elements.
How should nichrome wire be heated safely in class?
Use a current-limited low-voltage supply, fix the wire to heat-resistant terminals, and let it cool before handling, because it can become very hot.
