The following devices (table) are plugged into outlets on the same 120V circuit in a house. This circuit is protected with a 15-A circuit beaker.
| Device | Power |
| Computer | 250 W |
| Heater | 900 W |
| Toaster | 500 W |
| Stereo | 120 W |
a. Draw a circuit diagram for this situation
b. Find the current through each device, and then the total current. Is there too much current in the circuit. Is the circuit breaker tripped?
Homework Answers
There is not too much current in the circuit.
As the circuit breaker has the value of 15 A, which means it can tolerate current upto 15 A. So the circuit will not trip as the current flowing through the breaker is 14.747A.
