The three highest-power appliances that can be plugged into two outlets and be running at the same time are air conditioner, washing machine and popcorn popper.
The current of each appliance is calculated as follows;
P = IV
I = P/V
air conditioner (1000 W), I = 1000/120 = 8.33 A
refrigerator (450 W), I = 450/120 = 3.75 A
washing machine (500 W), I = 500/120 = 4.17 A
popcorn popper (250 W), I = 20/120 = 0.17 A
The three highest-power appliances that can be plugged into two outlets;
8.33 A + 4.17 A + 0.17 A = 12.67 A, which is less than 15 A.
Thus, the three highest-power appliances that can be plugged into two outlets and be running at the same time are air conditioner, washing machine and popcorn popper.
