Answer:Electrostatically charged rods. When you rub the plastic rod (polyethylene terephthalate, glycol modified, or PETG) with the wool cloth, the rod charges negative. When you rub the glass rod with the silk, the rod charges positive. ... The Coulomb, the unit of electrostatic charge, is named after him.
