Unit 3 lesson 1-5
Term | Definition |
---|---|
Electric charge | property that leads to electromagnetic interaction 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 |
semicondutor | special class of materials that conduct electric charge better than electric 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 |
resistance | the opposition to the flow of electric charge |
electric circuit | a complete, closed path through which electric charges can flow |
series circiut | all parts are connected in a row that forms one path for the electric charge to follow |
parallel circuit | electric charges have more than on path that they can follow |
magnet | to describe any material that attracts iron or objects made of iron |
magnetic force | when you bring two magnet 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 |
electrical insulater | a material through which charges cannot move easily |
electromagnetism | when electric currents and magnetic fields interact with each other. |
electromagnet | combines the magnetic field of the solenoid with the magnetic field of the magnetized iron core. |
