| A | B |
|---|
| power | the amount of work that is done in a certain period of time |
| kilowatt | large amounts of power- 1 kilowatt equals 1,000 watts |
| watts | small units of electric power |
| closed circuit | has electricity "ON" |
| insulator | not a good conductor of electricity |
| proton | particle in the nucleus that has a positive charge |
| atoms | small particle in everything--is microscopic |
| current electricity | the movement of electrons through metal and wires |
| nucleus | the center of an atom |
| electron | particles that zip around the nucleus and generate electricity--has a negative charge |
| electric discharge | movement of extra electrons--a "shock" |
| neutrons | particles in the nucleus with a neutral (no) charge |
| conductor | any material that an electric charge will easily pass through |
| How do atoms make electricity? | The electrons move from one atom to another |
| open circuit | no electric connection- "OFF" |
| static electricity | an electric charge that does not move through wires |
| generator | changes energy of motion into electrical energy |
| series circuit | one path for electricity (one goes out-they all go out!) |
| turbine | a device made up of a wheel and blades |
| parallel circuit | has 2 paths for electricity (a break still lets the rest work) |
| electric cell | a device that changes chemical electricity to an electric cell |
| mechanical energy | energy used to move machine parts |
| dry cell | a type of electric cell that uses a chemical paste |
| filament | thin coil of wire in a lightbulb |
| electric motor | a machine that changes electrical energy to mechanical energy |
| wet cell | a type of electric cell that uses acid and water |
