Asked by Andrea
If the TV draws a 150W of power, the dishwasher 1500 W of power and the computer 100 W of power, will a typical 15 A circuit breaker trip if they operate simultaneously on one line? Explain why.
Isn't P= IV and P=I^2R and P- V^2/R
So wouldn't that mean that as these three appliances are being used power increases so I will also increase causing the 15 A circuit breaker to trip. Also because they are operating simultaneously on one line wouldn't that mean they are in series so I throughout the circuit is the same?

The three appliances would be operating in parallel.
Total power drawn is 1750 W, which at 110 V (which is typical in the USA) corresponds to 15.9 A. At 115 V, it would be 15.2 A.
The breaker would probably trip.
