Conductor homework problem

  1. Oct 17, 2008 #1
    1. The problem statement, all variables and given/known data

    13) A large metallic sphere insulated from ground is charged
    with an electrostatic generator while a student standing on
    an insulating stool holds the sphere. Why is it safe to do
    this? Why would it not be safe for another person to touch
    the sphere after it had been charged?

    2. Relevant equations



    3. The attempt at a solution

    I know that the insolater will stop the current to flow for the first part of the question, but why if the person touches the sphere after charching is not safe??
    is it because the body acts as a conductor??? so the current will flow??

    Please help as fast as possible

    regards, Blackice

    If it's right, thank god
    but i want a scientific answer, and why exactly it's not safe !

    sorry for my bad spellings, because i wrote very fast and my mother language is not english :)

    correction ..

    insolater == insolator
    charging == charging

    Please be patient, you must realise that everyone is here voulterily and have other commitments besides Physics Forums.
    That's about as scientific as it gets.
