A toaster with a Nichrome heating element has a resistance of 70 ohms at 20oC and an initial current of 1.6 A. When the heating element reaches its final temperature, the current is 1.39 A. What is the final temperature of the heating element?
The Attempt at a Solution
I know that the voltage will remain constant therefore:
I also know that Nichrome's [tex]\alpha[/tex]=100e-8
but I don't really know where to go from here
