    Question 10 - M1 (18 marks) Many people use electric kettles in their houses to boil water (for example to make a cup of tea or coffee) These devices work by passing an electric current through a metal wire. As the electricity passes through the wire, it gets hot and this is the source of heat to boil the water. Consider the Kettle shown in the figure below. The electricity passes through a coiled 'resistance wire' which is housed within...

    A certain toaster has a heating element made of Nichrome resistance wire. When the toaster is first connected to a 140-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...
