Back to SCIENCE main page

  • Some insulating materials become electrically charged when they are rubbed together.

  • A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged.

  • Charges that are the same repel, while unlike charges attract.

  • Electrostatic precipitators, photocopiers and laser printers make practical use of electrostatic charges.

  • The study of static electricity is called electrostatics.
