| electric current | the flow of negative charges through matter |
| resistance | a measure of how much a material opposes the flow of electric current and changes electric current into heat energy |
| conductor | a material through which electric current passes easily |
| insulator | a material through which electric current does not pass easily |
| series circuit | a circuit that connects several objects one after another so that the current flows in a single path |
| parallel circuit | a circuit that connects several objects in a way that the current for each object has in its own path |
| electrical energy | the energy of charges in motion |
| static electricity | a form of potential electrical energy caused by the buildup or loss of electrons and the positive and negative charges no longer balance. |
| circuit | a complete, unbroken path that electrons can travel to do work |
| switch | a device that opens and closes a circuit to stop or start the movement of electrons |
