Charge on a Capacitor

  1. Oct 16, 2013 #1
    1. The problem statement, all variables and given/known data
    A battery is connected to a capacitor made from two conductors. Why do each of the two conductors acquire the same charge,regardless of size or shape?

    2. Relevant equations

    3. The attempt at a solution
    Well, I can see that this is sensible, intuitively that the charge on one will repel an equal amount of charge on the other. But I have no idea how to prove/represent this mathematically!
    Thanks for help! :)

    What does a battery do to charge?

    Apply a fixed potential to it, I suppose. But I'm not sure how that helps??

    How does it apply the fixed potential?
    What does it do to the charge to get that potential?
