Across
- 4. A body having the property of attracting iron and producing a magnetic field external to itself.
- 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.
- 11. An instrument for measuring in volts the differences in potential between different points of an electrical circuit.
- 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.
- 15. An instrument for measuring electric current, especially in amperes.
- 16. A complete electrical circuit around which current flows or a signal circulates.
- 21. Comprises branches so that the current divides and only part of it flows through any branch.
- 23. The energy generated by the movement of electrons from one point to another.
- 24. A flow of electric charge.
Down
- 1. An electrical circuit that's not complete.
- 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. That the current through a conductor between two point's directly proportional to the voltage across the two points.
- 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.
- 6. Electric potential or potential difference expressed in volts.
- 7. A combination of apparatus for producing a single electrical effect.
- 8. Ability to act or produce an effect.
- 9. A variable whose value/behavior is determined by that of one or more other variables in an experiment.
- 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.
- 13. Energy stored in the bonds of chemical compounds.
- 17. A material or object that permits an electric current to flow easily.
- 18. A simple pathway that lets electrons flow to one or more resistors.
- 19. A drawing or diagram.
- 20. A device that has electrical resistance and that's used in an electric circuit for production, operation, or current control.
- 22. Usable power.
