Rank the lightbulbs in order of brighness.
All lightbulbs are identical.
The Attempt at a Solution
A is brightest, then B=C, then D=E
B and C are the same brightness level because they are in parallel, D and E are the least bright because they are in series.
I even downloaded a circuit creator to verify my solution but apprently I am still not correct and I am not sure why. (program from PhET Interactive Simulations Copyright © 2004-2010 University of Colorado)
