Across
- 3. coil of wire acting as a magnet when carrying electric current
- 5. a path along which the whole current flows through each component.
- 7. energy realtive to its position
- 12. force exerted by magnets when they repel or attract each other
- 13. energy of oject either in motion or energy relative to objects position
- 17. an electric current that is uni-directional, so the flow of charge is always in the same direction
- 20. passive two-terminal electrical component that implements electrical resistance as a circuit element
- 21. the production of an electromotive force across an electrical conductor in a changing magnetic field.
- 22. attraction or repulsion that arises between electrically charged particles because of their motion
- 23. energy that is present due to motion
- 24. a material that conducts electricity through it
- 25. device that converts motive power into electric power for use in an external circuit
Down
- 1. comprises branches so that the current divides and only part of it flows through any branch
- 2. a material that does not conduct electricity
- 4. magnetic field is produced by an electric current
- 6. physical interaction among electric charges magnetic moments, and the electromagnetic field
- 8. instrument can detect and measure small amounts of current in an electrical circuit
- 9. points near extremities where lines of magnetic fields are directed
- 10. passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuit
- 11. force moving electrically particles in a circular or helical path
- 14. anything that has a urge to do something to to something
- 15. sticky thing that attracts stuff
- 16. stream of charged particles moving through an electrical conductor or space
- 18. device that creates mechanical energy by using electrical energy
- 19. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
