A toaster uses a nichrome heating wire when the toaster is


A toaster uses a Nichrome heating wire. When the toaster is turnedon at 20° C, the initial current is 1.50 A. A few secondslater, the toaster warms up and the current now has a value of 1.28A.

The average temperature coefficient of resistivity for Nichromewire is 4.50 10-4 (C°)−1.

What is the temperature of the heating wire?
