The following three appliances are connected to a 120-V house circuit: i)toaster,1 325 W,ii)coffee pot,650 W,and iii)microwave,600 W.If all were operated at the same time,what total current would they draw?
A)2.10 A
B)47.5 A
C)7.15 A
D)21.5 A
E)11.0 A

Question

Quizplus · Accepted Answer

The total power consumed by the appliances when operated simultaneously is the sum of their individual powers: 1325 W (toaster) + 650 W (coffee pot) + 600 W (microwave) = 2575 W. The total current drawn can be calculated using the formula I = P/V, where P is the total power and V is the voltage. Thus, I = 2575 W / 120 V = 21.4583 A, which rounds to 21.5 A.
