alleryOne bulb burns out in a series circuit. What happens to the other bulbs?
AThey go dark
BThey get brighter
CThey stay lit
DThey change colour
Answer & Solution
Correct answer: A. They go dark
1. A series circuit has one path, so a burnt-out bulb breaks the entire circuit.
2. The others therefore go dark, not brighter or unchanged.
3. Colour change has no basis.
