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. |
Semiconductors | 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 |
Voltage | The amount of work required to move each unit of chagre between two points. |
Electric Circuit | A complete, closed path through which electric charges can flow. |
Series Circuit | A in circuit in which all parts are connected in a row that forms one path for the electric charges to follow. |
Parallel Circuit | A circuit in which electric charges have more than one path that they can follow. |
Magnet | Any material that attracts iron or objects made of iron. |
Magnetic Force | When two magnets exert a push or pull. |
Magnetic Poles | The reason magnets can push each other away. |
Magnetic Field | The area were a magnet has magnetic force. |
