A mains appliance operates at 230 V and draws 5.0 A. What is its power?
Answer and explanation
Correct answer: D. 1150 W
- Step 1: P = IV.
- Step 2: 5.0 × 230 = 1150 W.
Answer
1150 W.
Why not the others: 46 W: the voltage was divided by the current. 235 W: the values were added. 0.022 W: the current was divided by the voltage.
