Question

A coffee maker is rated at 1290 W, atoaster at 1060 W, and a waffle maker at1490 W. The three appliances are connectedin parallel to a common 120 V household circuit. (a) What is the current in each appliance whenoperating independently? coffee maker 1 A toaster 2 A waffle maker 3A
(b) What total current is delivered to the appliances when all areoperating simultaneously?
4 A

(c) Is a 15-A circuit breaker sufficient in this situation?Explain.

Explanation / Answer

current in each is determined by:    I = P / V   so: . coffee maker   1290 / 120  =    10.75amps .    toaster         1060 /120 =    8.833amps . waffler          1490 / 120 =     12.42 amps .        total current =     32.0 amps . NO, a 15 amp breaker is not sufficient because if they areplugged in together they will exceed the 15 amp limit
