If there are two bulbs connected in series and one blows out, what happens to the other bulb?
Correct answer: B. The other bulb stops glowing
- A. The other bulb continues to glow with the same brightness
- B. The other bulb stops glowing
- C. The other bulb glows with increased brightness
- D. The other bulb also burns out
Explanation
If there are two bulbs connected in series and one blows out, the other bulb will stop glowing. This is because in a series circuit, the current flows through all of the components in the circuit, and if one component breaks the circuit, the current cannot flow through any of the components. When a bulb blows out, it acts as an open circuit, which means that the current cannot flow through it.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
