Three 60 W bulbs are in parallel across the 60 V power line. If one bulb burns open_________________?
Correct answer: D. the other two bulbs will light
- A. there will be heavy current in the main line
- B. rest of the two bulbs will not light
- C. all three bulbs will light
- D. the other two bulbs will light
Explanation
In a parallel circuit, each bulb has an independent branch across the supply. An open bulb disconnects only its own branch, so the other two continue to light.
