    1. The problem statement, all variables and given/known data

    L.B. = Lightbulb
    A,B,C are all identical light bulbs

    B = battery

    If a circuit looks like this

    -----L.B.A----------------
    | | |
    | | |
    | | |
    B L.B.B L.B.C
    | | |
    | | |
    | | |
    ------------------------

    What happens to brightness of A and C when B is removed?


    2. Relevant equations




    3. The attempt at a solution

    wow!! its not supposed to look like that!! ok let me describe it. There is a rectangle with a line down the middle. On the left side of the rectanlge is a battery. On the top left half of the rectange there is lightbulbA and on the line down the middle of the rectangle there is lightbulbB and on the right side of the rectangle there is lightbulbC.

    What happens to the brightness of A and C when B is removed?
