Four light bulbs (A, B, C, D) are connected together in a circuit of unknown arrangement. When each bulb is removed one at a time (and subsequently replaced), the following behavior is observed while it is removed:
A B C D
A rem * on on on
B rem on * on off
C rem off off * off
D rem on off on *
If a given electron passes through C, it must also pass through? what about B, which one will not pass through b?
