Four incandescent lamps are connected in series in a single circuit. If one of the lamp filaments burns out, what will happen to the other lamps?

🔍 Key Concepts

• series circuit vs parallel circuits • how current flows through a single continuous path • what happens to the circuit if the path is broken at any point

💭 Think About

• Visualize the four lamps as beads on a single wire loop. If one point in that loop opens, can current still travel through the rest of the loop? • Compare this to holiday lights wired in series: what happens when one bulb fails? • Think about whether the other lamps still have a complete circuit from the power source, through their filaments, and back to the source.

✅ Before You Answer

• Confirm whether a series circuit has only one path or multiple paths for current. • Decide if a burned‑out filament is effectively an open circuit (break) or a closed circuit (still conducting). • Check whether the remaining lamps still have a complete path for current after one filament opens.
