Magic of Electricity
Across
- 2. The rate of doing work.
- 4. A material that allows electrons to flow easily (with little resistance).
- 6. To draw to itself or oneself.
- 7. The flow of electricity along a conductor, measured in amperes.
- 10. A measure of the flow of electricity in a conductor.
- 12. The smallest portion of an element that cannot be changed.
- 18. Arrangement according to some orderly division into classes or groups.
- 20. A hard, silver-white metallic chemical element.
- 23. A device for storing electricity.
- 24. A form of energy, the flow of electrons, typically to produce light, heat, or to power a motor.
- 28. A part of an atom that carries a positive charge of electricity.
- 29. A magnetic material found on earth.
- 30. A part of an atom that has no electrical charge.
- 31. A hard, steel-grey metallic chemical element.
- 32. A standard measurement.
Down
- 1. Converts electric energy into mechanical energy.
- 3. The rotating part of an electric motor.
- 5. The characteristic properties possessed by magnets that involve forces of both attraction and repulsion.
- 8. Opposition to the flow of current in a circuit.
- 9. The opposite ends or sides of a magnet.
- 11. A material that attracts iron, nickel and other materials.
- 13. The part of a bulb which conducts current and produces light.
- 14. A material that provides a very high resistance to the flow of electrons.
- 15. Allows an electrical circuit to be opened (turned off).
- 16. The capacity or ability to do work.
- 17. To force away.
- 19. A device used to determine geographic direction.
- 21. A path for electricity to flow.
- 22. An educated guess that is tested by conducting experiments.
- 25. An iron core surrounded by a wire that temporarily becomes a magnet when an electric current flows through the wires.
- 26. A white, metallic chemical that can be readily magnetized.
- 27. The amount of force causing an electrical current to flow, usually measured as volts.
