Simple Model of Charges in an Insulator
Effect of Rubbing a Negatively Charged Ribbon
  • Note that the small vibrations of the negative charges are not shown and only the excess charges are shown.
  • Once the "essentially static" negative charges (the blue ones) on the charged ribbon are transferred to the insulating block, they remain essentially static at the position they get deposited at.
