About This Product
Resistance wire is used in physics lessons to study how the length and thickness of a conductor affect its resistance, and to make simple heating elements. The table of sizes shows the trend clearly: thicker wire has a lower resistance per metre, while thinner wire has a higher one. Nichrome is chosen for heating work because it is an alloy of nickel and chromium made for that purpose, as noted in the product details. School Lab Equipment India can export the Nichrome Wire 50g Reel to education buyers in Côte d'Ivoire, Bulgaria, Mexico, Tanzania and Ecuador.
