Homework Help: Designing a Parallel-plate capacitor

  1. Oct 14, 2007 #1
    1. The problem statement, all variables and given/known data

    Desgin a Parallel-plate capacitor with capcitance 47.0 pF and capacity 7.50nC. You have available conducting plates which can be cut to any size, and plexiglas sheet unsulation which can be cut to any size and machined to any thickness. Plexiglas has a dielectric constanr 3.40 and dielectric strength 4.00 * 10^7 N/C. You must make your capacitor as compact as possible in all directions. Specify all relevant dimensions. You may ignore fringing effects at the edges of the capacitor plates.

    2. Relevant equations

    3. The attempt at a solution

    Any ideas.

    Can you start by stating some equations that might be useful in determining how these factors relate to each other? You need to show of your own thoughts here as well.
