Term | Definition |
Electric Charge | property that leads to electromagnetic interactions between particles that make up matter |
Static Electricity | Buildup of electric charge on an object |
Electrical Conductor | material which charges can move freely |
Electrical Insulator | charges cannot move easily |
Semiconductor | special class of materials that conduct electric charge better than electric insulators but not as well as electric conductors. |
electric current | rate of flow of electric charges |
voltage | amount of work required to move each unit of charge between 2 points. |
resistance | opposition to the flow of electric charges |
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 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 | push or pull |
magnetic pole | 1 or 2 points that oppose magnetic qualities |
magnetic field | area surrounding a magnet where magnetic forces can be detected |
electromagnetism | interaction between electricity and magnetism |
solenoid | coil of wire that carries an electric current and therefore produces a magnetic field |
electromagnet | wrapping a solenoid around an iron core |
electric motor | changes energy to mechanical energy |
electromagnetic induction | using a magnetic field to create an electric current in a wire |
transformer | induction to increase of decrease the voltage of alternating current |
electric generator | induction to change mechanical energy into electrical energy |
electronic device | able to control the flow of electrons using integrated circuit |
integrated circuit | tiny chip of specially treated silicon containing many circuit parts |
