What happens to the remaining electric bulbs connected in a series circuit if one bulb burns out (blows)?
Answer and explanation
Correct answer: A. All remaining bulbs go off immediately
- Step 1: In a series circuit, there is only a single closed pathway for electric current to flow through. Step 2. If any component burns out, the conductive loop is broken (open circuit), and all current ceases to flow. Answer: All remaining bulbs go off immediately. Why not the others: Remaining bulbs cannot stay lit or shine brighter because current cannot bypass the severed filament in a series loop.
