Nichrome heating wire-what is temperature of heating wire

Reference no: EM13558185

A toaster uses a Nichrome heating wire. When the toaster is turned on at 20° C, the initial current is1.50 A. A few seconds later, the toaster warms up and the currentnow has a value of 1.24 A. The averagetemperature coefficient of resistivity for Nichrome wire is4.50 10^-4 (C°)⁻¹. What is the temperature of the heating wire?
