A device runs on 230 V and draws 10 A. What is its power?
Answer and explanation
Correct answer: B. 2300 W
- Step 1: Power = voltage x current. Step 2. 230 x 10 = 2300 W. Answer: 2300 W. Why not the others: 23 W: voltage was divided by current. 240 W: voltage and current were added. 4600 W: the power was doubled.
