| Term | Definition |
|---|---|
| electric charge | a property that leads the electromagnetic interactions 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 |
| 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 flow |
| parallel circuit | electric charges have more than one path they can follow |
