Three lights are connected in parallel across a 120 volt source. If one light burns out_____________?
Correct answer: D. the remaining two will glow with the same brightness as before
- A. the remaining two will glow dimmer
- B. the remaining two will glow brighter
- C. the remaining two will not light
- D. the remaining two will glow with the same brightness as before
Explanation
Each parallel light remains connected directly across the 120 V source, so one failed branch does not change the voltage across the other two. They therefore glow with the same brightness as before.
