Well, just wanted to stop by and say THANK YOU!
There was a 5 point (out of 100) problem regarding what happens to the midle bulb and I got it correct..not to mention I scored 98/100 on the test which is amazing considering I've never done that well in Physics before. The class average was a...
so when we close the switch the two upper lights remain same voltage but the two lower ones have lower voltage and the middle light has the same voltage as the upper lights? I'm not sure if this makes sense considering "same voltage acorss all elements in parallel" but it's 2 am here...so I'm...
so when the switch is open the four bulbs/resistors should be treated as parallel. (1/sum of left side) + (1/sum of right side) = (1/R total)
and when the switch is closed it should be treated as a series? (sum of left side) + (middle) + (sum of right side).
So the light bulbs on...
thanks for the reply...but why the question mark? I'm taking from your reply that the four "corner" lamps will light up before closing the switch and they will continue to light up after it is closed...but what about the middle lamp?
Thanks? lol
ok the diagram drawing isn't working...but here is a pdf file with the diagram

Hello,
I have a physics midterm on monday and this question is on the study guide so help with this problem would be greatly appreciated.
(ok, since this diagram isn't showing up properly, here is a pdf file that includes the diagram I am asking about...
