Question

The following three appliances are connected to a 120 volt house circuit: (i) a toaster, 1200 Watts, (ii) a coffee pot, 750 Watts, and (iii) a microwave, 600 Watt. If all operate at the same time, what total current would they draw

Answer 1

They would draw a total of 21.25 amperes

Step-by-step explanation:

The total power consumed is

1200 W+ 750 W + 600 W= 2550 Watts

The formula relating the power consumed, the voltage and the current is given as

`P=IV`---------------1

given that the voltage supply is 120V

`2550=I*120\\\I=(2550)/(120) \\\\I= 21.25amps`
