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 |
