Across
- 2. the difference in electrical charge between two points in a circuit expressed in volts.
- 3. A device that contains a rotating electromagnet that changes electrical energy to mechanical energy.
- 4. helps convert electric energy into mechanical energy. Uses a force to do so
- 5. Forms branches of which is a separate path for flow of electrons. One device breaking doesn’t affect entire circuit.
- 8. Rotating wire moves through a magnetic field, producing current in the wire
- 11. Basically the force behind each charge pushing it
- 12. The force of attraction or repulsion of a magnetic material due to the arrangement of its atoms, particularly electrons.
- 15. The attraction or repulsion between magnetic poles
- 16. A material that allows electrons to move easily through it.
- 18. When electric charges move. Basically the # of electrons that pass a certain point every second.
- 19. A looped or coiled wire carrying a current
- 20. The area near 2 magnets being either repelled or attracted. The magnetic field shows you whether or not the objects are being attracted.
- 21. Each end of the magnet
- 23. Has but a simple pathway through a series circuit. If one device fails, whole thing fails.
Down
- 1. produce currents in a wire. Wire rotates to produce current
- 6. Ferromagnet in middle of coil
- 7. Used to increase or decrease voltage
- 9. Charged particles create this..
- 10. A characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons
- 13. Any material that attracts iron or other materials that contain iron
- 14. Greatly increases strength of magnetic field produced by solenoid
- 17. The opposition to the flow of electrons through a conductor; measured in ohms.
- 22. A material that does not allow heat or electrons to move through it easily.
