Q1. In a simple battery-bulb circuit one wire breaks. Why does the bulb go out?
Answer: Current path is interrupted so charge flow stops
Explanation: In a simple series circuit, all components share a single unbroken conducting path; if that path is broken at any point — such as by a broken wire — the circuit is open and current ceases to flow everywhere, extinguishing the bulb. This is the fundamental limitation of series wiring.
