  17. In some circuits, electrical energy is transformed into light energy by a what?
  18. The wires in a circuit are made of a material that is a what?
  19. A path that electricity can follow is what?
    An electric circuit.
  20. A circuit in which electric charges can follow several different paths is called what?
    It is a parallel circuit.
  21. If a wire is disconnected, what kind of a circuit is it?
    An open circuit
  22. What is the covering on electric plugs and around wires made of?
    It is made of an insulator.
  23. What do you call a circuit in which all the devices are connected in a single path?
    It is a Series Circuit.
  24. When a light is on, it is a part of what circuit?
    It is a part of a closed circuit.
  25. What is a series circuit?
    An electric circuit in which the electric charges have only one path to follow.
  26. What is a parallel circuit?
    An electric circuit that has more than one path for the electric charges to follow.
  27. What is a material that resists the flow of electric charge?
    It is an insulator.
  28. What is a material that readily allows electric charges to pass through?
    It is a conductor.
  29. What is an electric circuit?
    It is a path along which electric charges can flow.
  30. For an electrical device to work, the circuit must form a complete loop. What is this called?
    A closed circuit.
  31. If a loose wire gets disconnected, the path is broken and charges cannot get through. What is this called?
    This circuit is an open circuit.
  32. What is a series circuit?
    It has only one path for electric charges to follow.

    if any part of the path breaks, the circuit is open.
  33. What is a parallel circuit?
    It is a circuit with several different paths for the charges to follow.

    If one part of the circuit breaks, the charges can still flow along the other parts.
  34. What is a circuit overload?
    It occurs when too many devices in a circuit are turned on.
