He turns on the coffee maker (average wattage 1200 W), puts some oatmeal in the microwave oven (1450 W) to cook, puts a couple of slices of bread in the toaster (1146 W), and starts making scrambled eggs in the electric frying pan (1196 W). All of these appliances in his dorm room are supplied by a 120 V (rms) branch circuit protected by a 50 A (rms) circuit breaker, will the breaker interrupt his breakfast? 2) The student’s roommate wakes up and turns on the air conditioner. He realizes that the room is a mess, so starts to vacuum. Now does the circuit breaker interrupt breakfast?
