My son in the 9th grade asked a question I can't seem to answer. He was
taught that current is a measure of charge in motion-so far so good, but
if you take a piece of glass and build up a charge by rubbing it and then
throw it are you not getting charge and motion ? I am in the electronics field
and told him no, but the more I think about the more I am not sure.
