An electric bulb is connected to 220 V generator. The current drawn is 600 mA. What is the power of the bulb?
- A. 132 W ✓
- B. 13.2 W
- C. 1320 W
- D. 13200 W
Correct Answer: A. 132 W
Explanation
Power P = V \times I. Given V = 220 \text{ V} and I = 600 \text{ mA} = 0.6 \text{ A}. Thus, P = 220 \times 0.6 = 132 \text{ W}.
