  6. 11. A circuit in which current flows in more than one closed path
  7. 14. A circuit in which current flows only in one closed path.
  8. 16. A scientific investigation in which one variable (the independent variable) is hanged, and all others are controlled, or kept the same.
  9. 18. An element or device in an electric circuit.
  10. 19. An instrument that measures electrical potential, or voltage, across a component or
