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 through 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. |
Electric Current | The rate of flow of electric charges. |
Resistance | The opposition to the flow of electric charge. |
Voltage | The amount of work required to move each unit of charge between two points. |
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 than one path that they can follow. |
Magnet | To describe any material that attracts iron or objects made of iron. |
Magnetic Force | When you bring two magnets together, they exert a push or pull. |
Magnetic Pole | Two magnets can push each other apart because of their ends. |
Magnetic Field | The area surrounding a magnet where magnetic forces can be detected. |
Electromagnetism | Results when electric currents and magnetic fields interact with each other. |
Electromagnet | Wrapping a solenoid around an iron core. |
