A certain toaster has a heating element made of Nichrome resistance wire. When the toaster is first connected to a 130-V source of potential difference (and the wire is at a temperature of 20.0°C), the initial current is 1.70 A, but the current begins to decrease as the resistive element warms up. When the toaster reaches its final operating temperature, the current has dropped to 1.53 A. (a) Find the power the toaster converts when it is at its operating...
