I cannot remember exactly what is the question. But i think the options are:Tom son:
[quote=\"Lol222\"]All bulbs are in parallel arrangement
i thought should be seires one cuz they ask for shine the brightest one
1: 2 batteries connected 4 bulbs in series. (The brightness of each bulb is 1/2 unit.)
2: 2 batteries connected to 4 bulbs where there are 2 circuits. (The brightness of each bulb is 1 unit)![](\"http://i60.tinypic.com/2my11ly.png\")

Tom son:
It's parallel circuit as all the bulbs will have equal brightness while for series circuit, some bulbs are bring while some bulbs are dim. Hence, parallel circuit is the answer.Lol222:
