Answers
1. A continuous flow of negative charges that create an electric current
2. Negative = electrons, positive = protons
3. Sunlight, wind, water, fossil fuel, nuclear power, and batteries
4. Produces light, heat, and sound for us to use. Run appliances, ovens, tvs and stereos
5. Conductor (many metals are good conductors)
Conductor = low resistance!!
Insulator = high resistance!!
6. A material that does not allow electricity to flow through it (ex. plastic, wood)
7. It describes how well electricity flows through a material.
8. Electrical wire like the ones found in your home
9. Volts (the force the electricity has)
10. Circuit
11. An energy source (battery), wire, and something to use the electricity (lightbulb)
12. closed circuit
13. A broken circuit that does not allow the electricity to flow all the way through
14. Series-there is one pathway for the current Parallel-There two or more pathways for the electricity
15. Ben Franklin- "Electricity in the air produces lightening."
Thomas Edison- Invented the light bulb and a device for recording sound
Michael Farraday - knows his electromagnets and built the first generator
16. Magnetic field
17. When 2 things rub together and electrons get swapped
