A toaster uses a nichrome heating wire. When the toaster is turned on at 20 degrees Celsius, the initial current is 1.5 amps. a few seconds later the toaster warms up and the current now has a value of 1.3amps. The average temperature coefficient of resisitivity for nichrome wire is 4.5X10^-4 (C)^-1. What is the temperature of the heating wire?
