Homework Help: Physics

Posted by Andrea on Thursday, April 3, 2008 at 5:55pm.

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?
