Variance between two parallel plate capacitors

  1. Mar 18, 2012 #1
    I have performed the Millikan oil drop experiment, but after a acquiring data for 14 drops it was impossible to collect anymore data because the drops would keep moving out of view under the influence of an electric field.

    The thing is I made sure that everything was as level as possible and I don't see what would change after the 14th drop.

    So I'm wondering is it possible for the charge distribution on a 4cm diameter capacitor plate to be not equally distributed throughout the surface of the material?

    edit*** could impurities cause this?
