1400 W. The three appliances are connected in parallel to a common 120-V household circuit. (a) What is

the current in each appliance when operated independently? (b) What total current is delivered to the

appliances when all are operating simultaneously? (c) Is a 15-A circuit breaker sufficient in this situation?

Explain.

a. do the math

b. add them

c. Hmmmm.

You ought to do engineering estimates first. 1200w is about 10 amp

1100 watts is about 10 amps

1400 watts is about 10 amps

That answers the last part pretty easily.
