- 2. A form of energy
- 4. an energy source that can only be used once and cannot be replaced, such as natural gas, petroleum, propane or coal.
- 5. A device that generates the flow of electrical energy (or power) in a circuit, such as a battery (or cells)
- 7. it; they act as magnets when electricity flows through them.
- 8. Circuit a path of electrical current that has more than one loop in the circuit
- 11. Objects with "like charges repel or separate (negative moves away from negative).
- 12. Objects with "unlike" charges move towards each other (positive attracts negative)
- 13. Electricity electricity that flows constantly in one direction on a closed path
- 14. A component or output device that converts electrical energy into light (lamp), heat (oven), sound (iPod) or motion (motor)
- 15. used to turn electricity on/off; stop/start electricity flow
- 16. A sub-atomic particle with a negative charge
Down
- 1. a material that does not allow electricity to pass through it
- 3. a temporary magnet made of an iron bar with coils of wire
- 5. Circuit a path of electrical current that passes through each device in the circuit; a path that has one loop
- 6. an energy source that can be used over and over or replaced, such as biomass, hydro, solar, wind or geothermal.
- 8. a particle with a positive charge equal to the negative charge of an electron
- 9. An uncharged particle (neutral) equal in weight to a proton
- 10. Electricity electricity that does not flow on a given path
- 13. a material that allows electricity to pass through it, such as a wire
