?A wire of Nichrome (a nickel –chromium– iron alloy commonly used in heating elements)
Chapter 26, Problem 17(choose chapter or problem)
A wire of Nichrome (a nickel –chromium– iron alloy commonly used in heating elements) is 1.0 m long and \(1.0 \mathrm{mm}^{2}\) in a cross-sectional area. It carries a current of 4.0 A when a 2.0 V potential difference is applied between its ends. Calculate the conductivity \(\sigma\) of Nichrome.
