EXERCISE Consider a heater rated at 120 V with power 2.8 kW. Hint (a) What is the resistance of the heater (in 0), and the current (in A) when it is under normal operation? R = I = A (b) If we connect it a 240 V source, assuming that it still works, what will be the actual power consumption now (in kW)? kW

What is the combined resistance of the three resistors in the diagram above?  Express your answer to two significant figures.
