Across
- 6. Description of an atom or molecule in which the changes are aligned so that one side has a slight excess of positive charge and the other side a slight excess of negative charge.
- 7. An electric current that repeatedly reverses its direction.
- 11. The electric potential energy per amount of charge.
- 13. Any material with very little or no free charged particles and through which current does not easily flow.
- 14. The amount of current in a circuit varies in direct proportion to the potential difference or voltage and inversely with resistance.
- 15. A material that can be made to behave sometimes as an insulator and sometimes as a conductor.
Down
- 1. The region of magnetic influence around a magnetic pole or around a moving charged particle.
- 2. Defined as a force per unit charge, it can be considered an energetic aura surrounding charged objects.
- 3. The rate of energy transfer, or rate of doing work.
- 4. The energy a charge possesses by virtue of its location in an electric field.
- 5. The property of material that resists the flow of electric charge through it.
- 8. A flow of charged particles that transports energy from one place to another.
- 9. An electric current that flows in one direction only.
- 10. A magnet whose field is produced by an electric current.
- 12. Any material having free charged particles that easily flow through it when an electrical force acts on them.
