Me and my group put together a cardboard house with four rooms: a bedroom, a bathroom, a living room, and a dining room. It featured circuitry with lights and switches to add a touch of atmosphere. Each room was nicely decorated and furnished. The bedroom featured cozy decor, while the bathroom was equipped with essential fixtures. The living room had a neat arrangement, and the dining room had a appealing table set for meals. In conclusion, the cardboard house offered a pleasant space.

a) If the light bulbs are in series, unscrewing one bulb would cause all the bulbs to turn off because they are connected in a single path, and removing one interrupts the flow of current.

b) If the light bulbs are in parallel, unscrewing one bulb would not affect the intensity of the others because each bulb has its own separate path for current flow.

c) The two bulbs connected in parallel would have the same intensity, while the bulb in series with them would have a different intensity.

d) If one bulb in parallel is unscrewed, the remaining bulb in parallel would maintain the same intensity, but the bulb in series would turn off.
