A toaster uses a Nicrhrome heating wire. When the toaster isturned on at 20o C, the initial current is 1.5A. A few seconds later, the toaster warms up and the current nowhas a value of 1.30A. The average temp coefficient ofresistivity for Nichrome is4.5x10-4(Co)-1. What is the temp of the heating wire?
