A certain toaster has a heating element made of Nichrome resistancewire. When the toaster is first connected to a 140 V source of potential difference (and the wireis at a temperature of 20.0°C), the initial current is 1.7 A.However, the current begins to decrease as the resistive elementwarms up. When the toaster reaches its final operating temperature,the current has dropped to 1.53 A.
