Question

The following appliances are being used simultaneously: toster oven, TV, computer, three 100 W light bulbs and an iron. Yet the circuit breaker (15 A) has not tripped. Does that necessarily mean that not all of these appliacnces are connected to a single circuit?

I am having trouble answering this question.

Answer 1

No. THe circuit breaker could be broken, or the appliances on different circuits.
