Across
- 1. these magnetic poles attract one another
- 8. the force between charged objects is ____ proportional to the square of the factor of change in the distance between the two objects
- 10. the amount of charge that travels past a fixed point in an electrical circuit each second
- 11. current that flows from the positive side of the battery to the negative side. This is the way current is drawn in circuit diagrams, even though it is wrong.
- 13. all devices on this type of circuit do not stop functioning when any one of them stops
- 15. all devices on this type of circuit will stop functioning when any one of them stops
- 16. electrical current is measured in this
- 18. charging an object without direct contact between the object and a charge
- 20. this tells you how hard the battery "pushes" electrons through a circuit
Down
- 2. when an atom loses electrons it becomes this charge
- 3. the ability of a material to impede the flow of charge open this type of circuit does not have a complete connection between the two sides of the power source. As a result, current does not flow
- 4. like charges do this to one another
- 5. the majority of light in creation is this to humans
- 6. this stores electrical charge
- 7. the force between charged objects is ____ proportional to the amount of electrical charge on each other.
- 9. opposite charges do this to one another
- 12. when an atom picks up extra electrons it becomes this charge
- 13. a small "package" of light that acts like a particle
- 14. these magnetic poles repel one another
- 17. a battery is symbolized with two ___ lines, one longer than the other
- 19. charging an object by allowing it to come into contact with an object that already has an electrical charge
