Electricity
Unit 3:Lessons 1-4
| Term | Definition |
|---|---|
| Electrical Charge | 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 | Material through which charges can move freely |
| Electrical Insulator | Material through which charges can't move easily |
| Semiconductor | Special class of materials that conduct electric charge better than electrical insulators but not as well as electrical conductors |
| Electric 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 | 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 than one path that they can follow |
| Magnet | Any material that attracts iron or objects made of iron |
| Magnetic force | Magnets exert a push or pull |
| Magnetic pole | Two magnets can push each other away because of their ends |
| Magnetic field | The area surrounding a magnet where magnetic forces can be detected |
| Electromagnetism | results when electric currents and magnet fields interact with each other |
| Electromagnet | Wrapping a solenoid around an iron core |
