Homework Help: Parallel-plate capacitor and work

  1. May 18, 2010 #1
    Disclaimer: Not very good at English terminology and notation so I've improvised and googled a bit, hope this isn't *too* poorly written to understand. Please correct me on my mistakes. :)

    1. The problem statement, all variables and given/known data

    The plates of of a paralell-plate capacitor have an area of 100 cm2 and are 3 cm apart. How much work is done if we slowly part them to a distance of 5 cm, if the plates are kept at a voltage 1000V? (a) What if the plates have been isolated during the experiment? (b)

    2. Relevant equations

    capacity=influence constant*area/distance
    charge= capacity * voltage
    F = charge * E

    3. The attempt at a solution
