Question: It is possible to charge a balloon to several thousand volts using electrostatics, for example, by rubbing it on one's hair or on different types of clothing. Does this mean that the balloon is also storing several Joules of energy? Why or why not?
Respond to the answer below.
Assuming that the charge is 1 coulomb. In that case it would be possible to negatively charge the balloon by rubbing it.
But because the charge rubbed on a balloon would typically be much much smaller than 1 coulomb. So in practice a balloon would probably not charge thousands of volts.
