Circuits question

  1. Sep 10, 2013 #1
    My question is regarding Vdb.
    for pos flow of charge

    Vbd = -Vdb
    and
    Vdb = -VR2
    so Vbd = VR2.

    This means that the current flowing from point d to point b gained potential energy. However the flow of charge from d to b are electrons and electrons lose potential energy as they move from lower to higher potentials. So when I look at it in that point of view
    Vbd should be equal to -VR2.

    Can someone clarify to me why I am wrong.

    Electrons are negatively charged, and flow in the opposite direction of the current.
