    Phototube and Voltage

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


    3. The attempt at a solution
    What I am wondering is if I found all of the answers for figure 1, wouldn't I just be repeating those same answers for figure 2 and 3? Or is the way it arranged important?
    Here are the values I found:
    Vc1=1.51V
    Vc2=1.61V
    Vc1c2=-0.1V
    Vc1a1=1.51V
    Vc2a2=1.61V
    Vc1a2=1.51V
    Va1=Va2=Va1a2=0
    Thanks for your help

    Alright, I figured out it wouldnt be the same for all figures.

    For figure one, I calculated Vc1=1.51 and Vc2=1.61. However, since they are connected to each other, they will reach the same potential Vc2=Vc1=1.56 and therefore Vc1c2=0

    My only question now really is can I relate Vc1 to Va2 in figure one? And would you relate the potentials of Va1 and Va2 in figure one as Va1a2=Va1c1-Va2c2?
