Across
- 6. An electric current which periodically reverses direction and changes its magnitude continuously with time
- 8. material in which electric current does not flow freely
- 9. a path along which the whole current flows through each component
- 11. comprises branches so that the current divides and only part of it flows through any branch
- 12. a passive two-terminal electrical component that implements electrical resistance as a circuit element
- 16. a device that converts motive power into electric power
- 19. the attraction or repulsion between magnetic poles
- 20. an electric current that is uni-directional, so the flow of charge is always in the same direction
Down
- 1. is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.
- 2. Is the force of atttraction or repulsion of a magnetic material due to the argument of its atoms particulary its electrons
- 3. a type of magnet in which the magnetic field is produced by an electric current
- 4. Total kinetic energy and potential energy of an object
- 5. is an object or type of material that allows the flow of charge in one or more directions.
- 7. a cylindrical coil of wire acting as a magnet when carrying electric current
- 10. the production of an electromotive force across an electrical conductor in a changing magnetic field
- 13. Any Material that attracts iron or other material that contain iron
- 14. the physical interaction among electric charges, magnetic moments, and the electromagnetic field a combination of invisible electric and magnetic fields of force.
- 15. Energy an object has due to its position
- 17. an instrument that can detect and measure small amounts of current in an electrical circuit.
- 18. Energy an object has due to its motion
