Three incandescent bulbs of $100\, W$ each are connected in series in an electric circuit. In another circuit,another set of three bulbs of the same wattage are connected in parallel to the same source. Now,if one bulb in both the circuits gets fused,will the rest of the bulbs continue to glow in each circuit? Give reasons.

(N/A) $1$. In the series circuit,the bulbs are connected in a single path. When one bulb fuses,the filament breaks,creating an open circuit. Consequently,the flow of current stops entirely,and all the remaining bulbs will stop glowing.
$2$. In the parallel circuit,each bulb is connected across the same potential difference independently. If one bulb fuses,it only affects its own branch. The other two bulbs remain connected to the source and will continue to glow with the same brightness as before.
