- A certain brand of hotdog cooker works by applying a potential difference of 122 V across opposite ends of a hot dog and allowing it to cook by means of the thermal energy produced. The current is 11.3 A, and the energy required to cook one hot dog is 62.4 kJ. If the rate at which energy is supplied is unchanged, how long will it take to cook three hot dogs simultaneously? Number i UnitsA coil of Nichrome wire is 26.0 m long. The wire has a diameter of 0.450 mm and is at 20.0°C.
