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 special class of materials that conduct charge better than electrical insulators but not as well as electrical conductors. |
Electric current | The rate of flow of electric charges |
Voltage | Is the amount of work required to move each unit of charge between two points |
Resitance | The opposition to the flow of electric charge |
Electric circuit | Is a complete, closed path. |
Series circuit | All parts are connected in a row that forms one path. |
Parallel | Electric charges have more than one path. |
Magnet | Describes any material that attracts iron. |
magnetic force | Exert or push on or pull on each other. |
Magnetic poles | two magnetic can push each other apart. |
Magnetic field | The area surrounding a magnet where magnetic forces can be detected. |
Electromagnetism | Results when electric currents and magnetic fields interact with each other. |
Electromagnet | Wrapping a solenoid around an iron core. |
