# Homework Help: Conductor homework problem

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??

regards, Blackice

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

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.
