Question

Circuit breakers are re-settable switches that protect us against a dangerously large total current by opening the circuit to stop the current at a specified safe value. A 1,650 W toaster, a 1,090 W iron and a 1,250 W microwave are plugged into a 120 V A.C. outlet which is connected to 20-Ampere circuit breaker. When all the appliances are turned on the breaker “kicks out”. Why did this happen and determine which two appliances may be used simultaneously.
