You and your roommates are studying hard for your physics exam. You study late into the night and then fall into your bed for some sleep. You all wake early before the exam and scramble groggily around making breakfast. You can’t agree on what to have, so one of you cooks waffles on a 990-watt waffle iron while another toasts bread in a 900-watt toaster. You want to make coffee with a 650-watt coffeemaker, and you plug it into the same power strip into which the waffle iron and toaster are plugged. Will the 20-A circuit breaker remain operational?
