Across
- 3. current=voltage divided by resistance
- 5. also know as voltage difference
- 6. measured in ohms
- 9. the region of magnetic influence around a pole or around a moving charged particle
- 10. a material that can be made to behave sometimes as an insulator and sometimes as a conductor
- 11. energy per amount of charge ,measured in volts,often called voltage
- 12. the si unit of electric charge
- 13. power=current times voltage
Down
- 1. magnet field is produced by an electrical current
- 2. any material having free charged particles that easily flow through it when an electrical force acts on them
- 4. the induction of voltage when a magnetic field changes with time
- 7. an electric current that flows in one direction only
- 8. any material with very little or no free charged particles
- 10. an electric circuit with devices connected in such a way that the same electric current exists in all of them
- 12. the relationship among force,charge,and distance
