Electric circuits problem (diagrams included)

    Basically I need to find the brightness of the labelled lamps relative to the original lamp.

    It is lamps c&d and g&h which are causing me the most trouble. Can anyone tell me what I should be looking for? I think redrawing the curcuit would be a good idea but I can't even do that.


    Any help would be much appreciated.

    Hint on c&d -- if c and its mirror image have normal brightness, what is the voltage across d?

    Oh yeah it would be 0v so the bulb d is off


    Any ideas on g and h?

    Sure. But we want to hear your thinking about it -- that's what's important.

    Poke at the problem some. What if g and its twin weren't there? What if h wasn't there? What are your thoughts about how to combine those two situations....?
