| Static electricity | The accumulation of excess electric charge on an object. |
| Law of conservation of charge | Charge can be transferred from object to object, but cannot be created or destroyed. |
| Conductor | Material in which electrons are able to move easily. |
| Insulator | Material in which electrons are not able to move easily |
| Charging by contact | The process of transferring charge by touching or rubbing. |
| Charging by induction | The rearrangement of electrons on a neutral object caused by a nearby charged object. |
| Electric current | Net movement of electic charges in a single direction |
| Voltage difference | Related to the force that causes eletric charges to flow |
| Circuit | Closed path that electric current follows. |
| Resistance | The tendency for a material to oppose the flow of electrons, changing eletrical energy into thermal energy and light. |
| Ohm's law | The current in a circuit equals the voltage difference divided by the resistance. |
| Series circuit | The current has only one loop to flow through |
| Paralle circuits | Contain two or more branches for current to move through |
| Electric power | Rate at which electrical energy is converted to another form of energy. |
