I Excess charge in capacitors connected in series

  1. Jul 20, 2017 #1
    I have a hard time comprehending excess charge in capacitor plates.
    Let's say we have two identical capacitor and we charged them to identical amount of charge.
    Next we connect them in series by opposite sign electrodes and we get double the voltage on the open ends.
    Now a single capacitor has excess charge on both plates in which one has excess electrons and the other excess of positive charge which originate from protons in nucleus.
    When connecting those two capacitors one electrode has excess of electrons and the other excess of positive charges yet no current flows up on connection. Also now we have two inner plates connected and there should be no excess charge on them since it is now one single pierce of conductive material...
    What really happens up on connecting of the two inner plates of charged capacitors and is there an excess of charge on them?

    Maybe, it will be helpful for an understanding when you search for something similar to “inserting metal into parallel plate capacitor”.

    Yes, I got it there are both positive and negative charges in equal amount displaced symmetrically by the fields in dielectric materials...
    Sorry about lame post...
