Unit 3 Lesson 1 2 3
Electric Charge and Static Electricity
| Term | Definition |
|---|---|
| Electric charge | a property that leads to electromagnetic interactions between the particles that make up matter |
| Static electricity | the buildup of electric charge of an object |
| Electrical conductor | a material through which charges can move freely |
| Electrical insulator | a material through which charges cannot move easily |
| Semiconductor | a special class of materials that conduct electric charge better than electrical insulators but not 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 |
| Resistance | the opposition to the flow of electric charge |
| Electric circuit | 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 so they can follow |
