Electric Charge and Static Elecricity
Term | Definition |
---|---|
electric charge | is a property that leads to electromagnetic interactions between the particles that make up matter. |
static electricity | is the buildup of electric charge on an object |
electrical conductor | is a material through which charges can move freely |
electrical insulator | is a material through which charges cannot move easily |
semiconductor | are a special class of materials that conduct electric charge better than electrical insulators but not as well as electrical conductors |
electric current | rate of flow of electric charges |
resistance | opposition to the flow of electric charge |
voltage | is the amount of work required to move each unit of charge between two units |
electric circuit | is a complete, closed path through which electric charges can flow |
series circuit | all parts are connected in a row that forms one path for the electric charges to follow |
parallel circuit | electric charges have more than one path that they can follow |
magnet | to describe any material that attracts iron or objects made of iron |
magnetic force | when you bring two magnets together they exert a push or pull |
magnetic pole | two magnets can pull each other apart because of their ends |
magnetic field | the area surrounding a magnet where magnetic forces can be detected |
electromagnetism | results when electric currents and magnetic fields interact with eachother |
electromagnet | wrapping a solenoid around an iron core |
