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 though 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 now as well as electrical conductors. |
Electric current | The rate of flow of electric charges is called. |
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 pat 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 from iron |
Magnetic force | When magnets exert a push or pull on each other |
Magnetic Poles | Two magnets can push each other apart because of their ends |
Magnetic field | The area surrounding a magnet where magnetic force can be detected |
Electromagnetism | Results when electric currents and magnetic fields interact with each other. |
Electromagnet | Wrapping a solenoid an iron core makes an electromagnet |
