Across
- 1. a three-dimensional region around a charged object that will apply a force on other charged objects within that region
- 4. the property of matter indicating the degree to which the material slows down the flow of charge carriers
- 5. electricity involving moving electric charges
- 6. when the current takes an unintended path – can be dangerous
- 13. the loop through which current electricity can flow
- 15. an accumulated electric charge on an object
- 16. a safety device for electric circuits that opens the circuit by melting when an overheated condition occurs due to excessive current
- 17. an electrical device that converts electrical energy into other forms, such as thermal energy
- 18. a safety device consisting of an automatic switch that opens when there is too much current in the circuit
- 19. the current in a circuit is directly related to the voltage and inversely related to the resistance
Down
- 2. materials through which charge moves easily
- 3. charge cannot be created nor destroyed but only transferred between objects
- 7. the act of providing a path for electric charge to move into the earth, or ground
- 8. movement of the electric charge through a complete loop
- 9. charges flow in one direction from the power source
- 10. opposite electric charges attract each other, while like charges repel each other
- 11. the “force” that moves electric charge carriers through an electric circuit
- 12. electric charges in these circuits change direction repeatedly as the system operates
- 14. materials through which charge does not move easily
