If many bulbs are connected in series in a circuit, and if one bulb blows off, what happens to the other bulbs?

Correct option is C

The correct answer is (c) All the other bulbs stop glowing.
· In a series circuit, if one bulb blows off, it breaks the circuit, causing all the other bulbs to stop glowing because the flow of electric current is interrupted.
Other Options:
· A few bulbs burst: Incorrect, bulbs don’t burst when one goes out.
· Some bulbs glow and some do not glow: This would happen in a parallel circuit, not in a series circuit.
· All the other bulbs glow: This would also happen in a parallel circuit, not in a series circuit.
