In a dorm, there are a few electric devices running at a voltage of 110 V. A refrigerator that runs with a current of 4.0 A, a heater with a resistor of 10 Ω at room temperature, a fan that exerts 12 Nm toque with a constant angular velocity of 8 rad/s. What is the total power? If the resistor in the heater has a temperature dependence with α = 0.01. When the heater reaches 500 ̊C, what is the change in total power in the dorm?
