Across
- 3. a device for making and breaking the connection in an electric circuit.
- 4. a set of electrical components connected such that they provide one or more complete paths for the movement of charges.
- 5. a coil of wire with an electric current in it.
- 6. a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
- 8. of Energy the law that states that energy cannot be created or destroyed but can be changed from one to another.
- 10. the interaction between electricity and magnetism.
- 15. a device that transforms mechanical energy into electrical energy.
- 17. a circuit in which the parts are joined one after another such that the current in each part is the same.
- 19. a circuit in which the parts are joined in branches such that the voltage across each part is the same.
- 22. a force under the influence of which objects tend to move away from each other.
- 23. a current consisting of charges that flow in only one direction in a circuit.
- 25. the region around a magnet where the magnetic force is exerted.
Down
- 1. an electrical circuit that is not complete.
- 2. is the study or matter, which is anything that takes up space and has mass, and the study of energy, which is the ability to cause change.
- 7. a device that increases or decreases voltage, which often consists of two separate coils of insulated wire, wrapped around an iron core.
- 9. a current consisting of charges that move back and forth in a circuit.
- 11. a force produced when magnetic poles interact.
- 12. the energy of an object that is due to the objects motion.
- 13. any material that attracts iron or materials containing iron.
- 14. a force which makes things move together or stay together
- 16. a wound spiral of two or more turns of insulated wire, used to introduce inductance into a circuit.
- 18. the refusal to accept or comply with something; the attempt to prevent something by action; opposition to the flow of current in an electric circuit
- 20. a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
- 21. the attractive force between objects, the force that moves objects downhill.
- 24. a complete electrical connection around which current flows or circulates.
