| Term | Definition |
|---|---|
| Static Electricity | The accumulation of excess electric charge on an object. |
| Law of Conservation of Energy | States that energy can never by created or destroyed. |
| Conductor | Material, such as copper wire, in which electrons can move easily. |
| Insulator | Material in which electron are not able to move easily |
| Charging by Conctact | Process of transferring charge between objects by touching or rubbing |
| Charging by Induction | Process of rearranging electrons on a neutral object by bringing a charged object close to it. |
| Electric Current | The net movement of electric charges in a single direction, measured in amperes. |
| Voltage Difference | Related to the force that causes electric charges to flow; measured in volts. |
| Circuit | Closed conducting loop through which an electric current can flow. |
| Resistance | Tendency for a material to oppose electron flow and change electrical energy into thermal energy and light; measured in ohms. |
| Ohm's Law | States that the current in a circuit equals the voyage difference divided by the resistance. |
| Series Ciruit | Circuit in which electric current has only one path to follow. |
| Parallel Circuit | Circuit in which electric current has more than one path to follow. |
| Electrical Power | The rate at which electrical energy is converted to another form of energy. |
