  • What is a circuit?
    The path energy/electrons flows along
  • What is the free movement of electrons called?
    Electricity
  • What can be classified as an insulator? Define this term with reference to flow of electrons
    An insulator does not allow the free flow of electrons through it
  • Name this circuit. Parallel or series circuit.
    Parallel
  • Uninsulated wires are safe. True or false
    False
  • Which shows a higher current? The red or the blue ?
    Red
  • What is it called when you walk across the floor and then try to open the door and get shocked?
    Static electricity
  • What energy is converted to electrical potential energy in a battery?
    Chemical potential energy
  • What is the Law of Conservation say about energy around us?
    Cannot be created or destroyed but can change form
  • Which wire would have the greatest resistance? The short or the long one?
    Long
  • What can be classified as a conductor? Define this term with reference to the flow of electrons.
    A conductor allows electrons to flow freely through it
  • Which part of the atom is locked into position and which part is not locked into position?
    Protons are locked in and electrons are not locked in and can move
  • Which is the better circuit? Series OR parallel circuit
    Depends on what it is needed for
  • Current is the movement of electrons through an area over a given time? True OR false
    True
  • How can a hotter temperature effect the flow of electrons?
    Faster flow as warmer temperature
  • Can electrons move between atoms? Yes or no
    Yes
  • What is a disadvantage of a series circuit?
    If one part does not work then the whole does not work
