A toaster uses a heating wire. When the toaster is turned on at 20 degree C, the initial current is 1.54 A. A few seconds later, the toaster warms up and the current has a value of 1.23 A. The average temperature coefficient of resistivity for this wire is 6.2 times 10-4 (C degree)-1. What is the temperature of the heating wire? Number Units
