The following three appliances are connected to a 120-V house circuit: i)toaster,1 200 W,ii)coffee pot,750 W,and iii)microwave,800 W.If all were operated at the same time,what total current would they draw?
A)3.0 A
B)5.0 A
C)10 A
D)23 A

To find the total current, we need to use the formula:

I = P/V

where I is the current, P is the power in watts, and V is the voltage.

For each appliance:

- Toaster: I = 1200/120 = 10 A 
- Coffee pot: I = 750/120 = 6.25 A 
- Microwave: I = 800/120 = 6.67 A

To find the total current, we add the current for each appliance:

10 A + 6.25 A + 6.67 A = 23 A

Therefore, the correct answer is D: 23 A.
