Electricity and Magnetism
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 on an object |
electrical conductor | a material through which charges can move freely |
electrical insulator | a material through which charges cannot move easily |
semiconductors | 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 that they can follow |
