Fields & Static

  • Charged objects in an electric field experience a force
  • The electric field helps to explain the non-contact force between charged objects
    • This is because the electric field cannot be seen, but can be detected by another charged object that moves within that field due to the electric force

  • This is a non-contact force because the charged objects do not touch for the force to be exerted

Positive and negative charges will travel towards the opposite charge, creating a spark

  • If an electric field becomes strong enough, the charges are forced through insulators such as air, creating a spark
    • This is what happens for example, when a charged person touches a conductor

  • The charged particles will travel towards the area with the opposite charge
