  2. What do you call a charge that stays on an object?
    static electricity
  3. Which kind of charges move? positive or negative
  4. How do 2 objects with different charges react to each other?
    They attract, or pull each other.
  5. How do 2 objects with the same charge react toward each other?
    They repel, or push away from each other.
  6. What are the parts of the circuit system in a flashlight?
    battery, switch, and a lightbulb
  7. Why does one disconnected bulb cause the other lights to go out in a series circuit?
    There is only one path for the current to follow.
  8. How does removing one bulb from a parallel circuit affect other bulbs in the circuit?
    The other bulbs can still light because current continues to flow along the path.

  17. supplies energy to move charges through a circuit
    electric cell
  18. a material that current can pass through easily
  19. an example of a conductor
    the base of a bulb
  20. a material that current cannot pass through easily
  21. example of insulator
    a coat
  22. a material that resists but doesn't stop the flow of current
  23. a circuit that has only one path for the current
