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 |
