Electricity

1. The degree to which a substance resists electric current
5. A temporary magnet formed when electric current flows through a wire or other conductor
7. A material that opposes the flow of electric current
8. A material through which electric current flows easily
9. A device that uses chemicals to generate and store electricity
10. The change in energy from one type to another as in a battery, which changes chemical energy to electricity
14. An electric circuit element used to store charge temporarily
15. Unit of electrical resistance used to measure a material's resistance to the flow of electric current
16. A form of energy produced by the flow or accumulation of electrons
17. An atom or group of atoms that has either gained or lost electrons and so has an electrical change
18. A device used to control current by providing resistance
19. A subatomic particle with a negative electrical change

2. Materials that lose all resistance to the flow of current at low temperatures
3. Unit of potential difference (similar to pressure)
4. The movement of electrons from one place to another either by current of static
6. Unit of power equal to volts x amps
11. The number of electrons that pass a given point at a given time
12. A process by which substances give off light or another form of electromagnetic radiation when they absorb energy
13. The effect by which an object begins to glow when heated
20. A path of conductors that an electric current follows
