Rank the brightness of five bulbs (3 different circuits) considering all the batteries and light bulbs are identical.
1st circuit - 1 battery hooked to bulb A.
2nd circuit - 1 battery with positive end hooks to bulb B then bulb B connects to bulb C then comes back to negative side of battery. (series)
3rd circuit - 2 batteries (series) with positive end of first battery hooks to bulb D then bulb D connects to bulb E then comes back to negative side of other battery.

I think I am missing something really important...question seems to be so...simple!
