Conductance of 2 bodies

  1. Apr 9, 2013 #1
    1. The problem statement, all variables and given/known data

    I have 2 arbitrarily shaped conductors with charge Q1 and Q2 with potetials V1 and V2 respectively. I then short them (connect with a thin metallic thread) now i have to prove that the amount of charge that flows from one to the other is: Only dependent on the geometry of the conductors.

    2. Relevant equations

    Does this behave like a capacitor, if so how?

    The voltages are with respect to something. There is capacitance between themselves and that something.

    yes but how do i prove the original question? that charge transferred is independent of all factors except geometry and potential difference?

    Perhaps look at the equation for a parallel plate capacitor. In particular the units. If the current depends only on quantities measured in meters or square meters then you've proved it depends on geometry.
