Across
- 2. states that the current in a circuit equals the voltage difference divided by the resistance
- 7. circuit in which electric current has more than one path to follow
- 9. a continuous flow of electric charge (electrically charged particles), which is measured in amperes
- 11. related to the force that causes electric charges to flow; measured in volts
- 13. is the flow of electrical power or charge
- 14. circuit in which electric current has only one path to follow
- 16. group of atoms with aligned magnetic fields
- 17. region surrounding a magnet that exerts a force on other magnets and objects made out of magnetic material
- 18. path along which an electrical current can flow
- 19. electric current that reverses its direction of flow in a regular pattern
Down
- 1. the buildup of electric charge in an object caused by the uneven distribution of charged particles
- 3. the conversion of a magnetic object into a magnet
- 4. device that uses an electric current to produce motion
- 5. electric current that only flows in one direction
- 6. a magnet created by wrapping a current-carrying wire around an iron core
- 8. the process by which electric current is produced in a wire loop by a changing magnetic field
- 10. an area surrounding a charged object, within which the object can exert a force on another object without touching it
- 12. device that uses electromagnetic induction to convert mechanical energy to electrical energy
- 15. the property of a material that determines how easily a charge can move through it
