Physics / Static Electricity

  • Do you know what is common between an electric eel, a bolt of lightning, and a glowing bulb? It is electricity !
         --An electric eel is a fish that makes its own electricity ,
         --Lightning is spark of electricity in the air and
         --bulb uses electricity to glow.
    Electricity is a form of energy produced by charges.
  • These charges can be at rest or moving. Let's find out how charges can be at rest or why they are moving.
         --Comb rubbed with hair gains electrons becomes negatively charged, attracts pieces of paper- Here charges are transferred from one body to another and remain at rest on surface of body -
            This is static electricity .
         --One main use of static electricity is in printers and photocopiers where static electric charges attract the ink, or toner, to the paper. Other uses include paint sprayers, air filters and dust removal.
  • Learn about how these charges can be transferred by different methods -
           1) Charging by friction
           2) charging by conduction
           3) Charging by induction
  • American, Benjamin Franklin carried out extensive electricity research in the 18th century, inventing the lightning rod amongst his many discoveries.
    Lightning rods protect buildings in the event of lightning by conducting lightning strikes through a grounded wire. A spark of static electricity can measure thousands of volts, but has very little current and lasts for a short period of time. This means it has little power or energy.
  • Learn such interesting facts related to your world.
