  2. 6. an electrical component that is used for controlling temperature and voltage
  3. 8. a single electrical source that uses chemical reactions to produce a current
  4. 9. an electrical component that is used for controlling temperature and voltage
  5. 11. any various substances that block the flow of electrical or thermal currents
  6. 12. a quantity whose value can change
  7. 13. an electrical component that allows the flow of current in only one direction
  8. 14. a characteristic of a unit of matter that expresses the extent to which it has fewer electrons than protons a stable subatomic particle that has a positive charge
  9. 16. the ability to exert a force causing displacement of an object
  10. 17. a measure of the rate at which work is done
Down

  5. 7. a measure of the opposition to current flow in an electrical circuit
  6. 8. an object or type of material that allows the flow of charge
  7. 10. emits light
  8. 15. a type of circuit in which resistors are arranged in a chain so the current has one path to take
