Across
- 6. a force exerted by magnets
- 9. created by gas particles moving and hitting things
- 12. a magnet with increased strength
- 14. the ray of light that strikes the surface before reflection
- 16. the current stays the same around this type of circuit
- 17. when the light source is small this is the area behind the object
- 18. Thomas Edison found this
- 19. two magnets with different poles do this
- 22. measured in amps
Down
- 1. gives off light
- 2. a solution which conducts electricity
- 3. measured in volts
- 4. the voltage of the cell is the same in each branch of this circuit
- 5. what a magnet is made up of
- 7. melts if the current through a circuit is too high
- 8. magnets and the earth have this in common
- 10. the light surrounding the umbra
- 11. pushing down on me pushing down on you
- 13. worked out when you multiply pressure by area
- 15. the angle used to compare the angle of incidence and reflection
- 16. light rays reflected in the same direction
- 20. two magnets with the same poles do this
- 21. composed of individual electronic components
