Worked Solution & Example Answer:h) (i) If a bulb ‘blows’ (fails) in circuit A does the second bulb stay on (glowing)? Give a reason for your answer - Junior Cycle Science - Question h - 2009
Step 1
If a bulb ‘blows’ (fails) in circuit A does the second bulb stay on (glowing)?
Answer
Yes, the second bulb stays on. This is because the bulbs are arranged in parallel, providing two paths for current. If one path is not functioning due to the blown bulb, the other path still allows current to flow, keeping the second bulb glowing.
Step 2
If a bulb ‘blows’ (fails) in circuit B does the second bulb stay on (glowing)?
Answer
No, the second bulb does not stay on. This is because the bulbs in circuit B are arranged in series. In a series configuration, if one bulb fails, it breaks the single path for current, preventing any of the bulbs from glowing.
