unit 3 lesson1-4
Term | Definition |
---|---|
Electric 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 move more freely |
electrical insulator | material through which charges cant move freely |
semiconductor | conduct electric charge better than electrical insulators but not as well 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 |
resostance | opposition to the flow of electric charges to move freely |
electric circuit | complete closed path through which electric charges flow |
series circuit | all parts are connected in a row that forms one pat for electric charges to follow |
parallel circuit | electric charges have more than one path that they can follow |
magnet | material that attracts iron or objects made of iron |
magnetic force | two magnets that exert a push or a pull |
magnetic pole | two magnets that push apart |
magnetic field | magnetic forces can be detected |
electromagnetism | relationship between electricity and magnetism results when electric currents and magnetic fields interact |
electromagnet | wrapping a solenoid around an iron core |
