static electricity | buildup of electric charge on an object |
electrical conductor | material through which charges can move freely |
electricaal insulator | material through which charges can't move freely |
semiconductor | special class of material that conduct electric charge better than electrical insulators but not as well as electrical conductors |
electric current | rate of flow of electric charges |
resistance | opposition to the flow of electric charges |
voltage | amount of work requird to move each unit charge between two points |
electric circuit | 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 follow |
parallel circuit | electric charges have more than one path that they can follow |
