in a bedroom inside a standard house, the owner has the following items connected to a circuit that is using 14 - gauge wire.
a laptop (250 w)
19 inch color tv (70 w)
a humidifier (1000 w)
unfortunately, an earthquake hits and the 19 inch tv is destroyed. the owner is given a new plasma tv. this tv now requires a cable box in order for the owner to watch his favorite tv shows. what is the load on the circuit now?
1560 w
1498 w
1568 w
1490 w

Explanation:

Step1: Identify relevant items

The relevant items are laptop (\(250\) W), humidifier (\(1000\) W), Plasma TV (\(240\) W), and Cable Box (\(8\) W).

Step2: Calculate total load

Add the wattages: \(250 + 1000+240 + 8\).
First, \(250+1000 = 1250\).
Then, \(1250+240=1490\).
Finally, \(1490 + 8=1498\).

Answer:

\(1498\) W
