  • Purpose: Study the nature of electric charge in a qualitative
    fashion.
  • Charging a rod: to create a positivley charged rod rub glass with silk; to create a negatively charged rod rub teflon with fake fur (the blue stuff).
  • To determine the conductivity of an object: Charge the electroscope, then touch the electroscope top (metal sphere) with the object. If the object is an insulator the electroscope will not respond to the touch.
