A certain toaster has a heating element made of Nichrome wire. When the toaster is first connected to a 110-V source (and the wire is at a temperature of 20.0°C), the initial current is 1.61 A. The current decreases as the heating element warms up. When the toaster reaches its final operating temperature, the current is 1.55 A. (a) Find the power delivered to the toaster when it is at its operating temperature.    (b) What is the final temperature of the heating element?
