static shock

As you walk across a carpet, electrons move from the rug to you.

    • Now you have extra electrons and a negative static charge.
  • Touch a door knob and ZAP!
    • The door knob is a conductor. The electrons jump from you to the knob, and you feel the static shock.
    • The electrons lose energy very quickly in the form of light and sound, as well as work done on you
  • We usually only notice static electricity in the winter when the air is very dry.
    • During the summer, the air is more humid. The water in the air helps electrons move off you more quickly, so you can not build up as big a static charge.

Scientists are not sure why charges separate between Earth and sky

    • During thunderstorms Earth’s surface becomes positively charged and electrons build up within the clouds
      • Positive charge will tend to build up in conductors
    • When there is enough build up of charge and enough energy, electrons move to neutralize with the protons on Earth
    • The light and sound occur as the energy is released.
