1. The problem statement, all variables and given/known data http://img522.imageshack.us/img522/9016/circuitsel3.jpg [Broken] http://g.imageshack.us/img522/circuitsel3.jpg/1/ [Broken] 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.
