Two copper metal plates separated and charged

  1. Nov 29, 2007 #1
    1. The problem statement, all variables and given/known data

    Two 10-cm-diameter metal plates are 1.0 cm apart. They are charged to +/-12.5 nC. They are suddenly connected together by a 0.224-mm-diameter copper wire stretched taut from the center of one plate to the center of the other.

    A)What is the maximum current in the wire?
    B)What is the largest electric field in the wire?
    c)What is the total amount of energy dissipated in the wire?

    2. Relevant equations

    really have no clue on this one, i think maybe i have to combine a capacitance equation, with something, or use that somehow to find the current.

    i do know that energy=.5C(Vc^2), but i cant see how to translate this to energy that goes into the wire.

    3. The attempt at a solution

    any advice on how to attempt this would be great
