A toaster uses a nichrome heating wire

Reference no: EM13557993

A toaster uses a heating wire. When the toaster is turned on at 13°C, the initial current is 2.13 A. A few seconds later, thetoaster warms up and the current has a value of 1.59 A. The averagetemperature coefficient of resistivity for this wire is 3.6 x10-4 (C°)-1. What is the temperatureof the heating wire?
