Unit 3, Lesson 1-4
Electricity and Magnetism
| Term | Definition |
|---|---|
| Electric Charge | A property that leads to electromagnetic interactions between the particles that make up matter. |
| Static electricity | The buildup of electric charge on an object. |
| Electrical conductor | A material through which charges can move freely. |
| Electrical insulator | A material though which charges cannot move easily. |
| Semiconductor | A special class of materials that conduct electric charge better than electrical insulators, but not as well as electrical conductors. |
| Electrical current | The rate of flow of electric charges. |
| Voltage | The amount of work required to move each unit of charge between two points. |
| Resistance | The opposition to the flow of electric charge. |
| Electric circuit | A complete, closed path through which electric charges can flow. |
| Series circuit | All parts are connected in a row that forms one path for the electric charges to follow. |
| Parallel circuit | Electric charges have more that one path that they can follow. |
| Magnet | Any material that attracts iron or objects made of iron. |
| Magnetic force | A push or pull. |
| Magnetic pole | The ends. |
| Magnetic field | The area surrounding a magnet where magnetic forces can be detected. |
| Electromagnetism | When electric currents and magenetic fields interact with eachother. |
| Electromagnet | A solenoid around an iron core. |
