  1. 4. A body having the property of attracting iron and producing a magnetic field external to itself.
  2. 10. variable A variable that's independent of the other variables in an experiment and whose value/behavior determines one or more of the values/behaviors of the other variables.
  3. 11. An instrument for measuring in volts the differences in potential between different points of an electrical circuit.
  4. 14. The practical meter-kilogram-second unit of electric current that's equivalent to a flow of one coulomb per second or to the steady current produced by one volt applied across a resistance of one ohm.
  5. 15. An instrument for measuring electric current, especially in amperes.
  6. 16. A complete electrical circuit around which current flows or a signal circulates.
  7. 21. Comprises branches so that the current divides and only part of it flows through any branch.
  8. 23. The energy generated by the movement of electrons from one point to another.
  9. 24. A flow of electric charge.
Down
  1. 1. An electrical circuit that's not complete.
  2. 2. An experiment in which all the variable factors in an experimental group and a comparison control group're kept the same except for one variable factor in the experimental that's changed or altered.
  3. 3. That the current through a conductor between two point's directly proportional to the voltage across the two points.
  4. 5. A fundamental form of energy observable in positive and negative forms that occurs naturally or is produced and that's expressed in terms of movement and introduction of electrons.
  5. 6. Electric potential or potential difference expressed in volts.
  6. 7. A combination of apparatus for producing a single electrical effect.
  7. 8. Ability to act or produce an effect.
  8. 9. A variable whose value/behavior is determined by that of one or more other variables in an experiment.
  9. 12. The practical meter-kilogram-second unit of the electrical potential difference and electromotive force equal to the difference of potential between two points in a conducting wire carrying a constant current of one ampere when the power dissipated between these two points is equal to one watt and equivalent to the potential difference across a resistance of one ohm when one ampere's flowing through it.
  10. 13. Energy stored in the bonds of chemical compounds.
  11. 17. A material or object that permits an electric current to flow easily.
  12. 18. A simple pathway that lets electrons flow to one or more resistors.
  13. 19. A drawing or diagram.
  14. 20. A device that has electrical resistance and that's used in an electric circuit for production, operation, or current control.
  15. 22. Usable power.
