Closing a Circuit

  1. Jan 24, 2012 #1
    1. The problem statement, all variables and given/known data

    Which combination(s) would allow the circuit below to turn on the light?

    S1 = A and S2 = B
    S1 = B and S2 = A
    S1 = B and S2 = B
    S1 = A and S2 = A

    3. The attempt at a solution

    I'm thinking that it would be true for the third and fourth ones when S1 and S2 are the same, so the current can flow through both switches. Otherwise, the circuit wouldn't be closed, no?
