Electricity

4. Negative charge freely moving
8. Electrical Current is measured in
9. Opposite charges
11. Flow of electrons through a material
14. where electrons flow in the same direction in the wire
16. water (a polar molecule) vapor in the air pulls electrons off negatively charged objects, preventing static charges to build up
18. Neutral charge
20. the opposition to the flow of electricity

1. transferred from rubbing i.e. get shocked after walking on the carpet
2. the force field of a highly negatively charged object pushes the electrons away from nearby objects causing them to become + charged,they then are attracted to each other. i.e. statically charged balloon attracts small pieces of torn up paper
3. Resistance=voltage/current
5. objects reaching static equilibrium
6. causes current to flow through an electrical circuit
7. When electrons move toward this equilibrium
10. electrons flow in different directions in a wire
12. resists the flow of electrons
13. Positive charge stuck in the nucleus
15. Allow the easy flow of electricity
17. transferred by direct contact w/ another object – hair standing on end w/ Van de Graff machine
19. Like charges
