Question

how do the lights in a series circuit behave when one bulb burns out?
the rest of the bulbs continue to shine at maximum brightness.
the rest of the bulbs continue to shine at a lower brightness.
the rest of the bulbs continue to shine at a higher brightness.
the rest of the bulbs stop shining and shut off.

Explanation:

In a series circuit, the components are connected in a single path for current flow. If one bulb burns out (opens the circuit), the entire circuit is broken, and current can no longer flow through any of the components. So all other bulbs in the series circuit will stop shining as there's no current to power them.

Answer:

D. The rest of the bulbs stop shining and shut off.
