A 1200W load on a 120V supply draws how many amperes?

Explanation:
The current a load draws is found from I = P / V. With a 1200 W load on a 120 V supply, I = 1200 W ÷ 120 V = 10 A. So the circuit carries 10 amperes under these conditions. The other options would require different power at 120 V (for example, 5 A would be 600 W, 15 A would be 1800 W, and 20 A would be 2400 W), which isn’t the given scenario.
