| Term | Definition |
|---|---|
| static electricity | The accumulation of excess electric charge on an object. |
| Law of Conservation of Charge | Charge can be transferred from object to object. |
| conductor | A material in which electrons are able to move easily. |
| insulator | A material in which electrons are not able to move easily. |
| Charging by contact | The process of transferring charge by touching or rubbing. |
| Charging by induciton | The rearrangement of electrons on a neutral object caused by a nearby charged object. |
| Electric current | The net movement of electric charges in a single direction. |
| Voltage Difference | is related to the force that causes electrical charges to flow. |
| circuit | A closed path that electric current follows. |
| resistance | is the tendency for a material to oppose the flow of electrons,changing electrical energy into thermal energy and light. |
| Ohms 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. |
| Parallel circuit | contain 2 or more branches for current to move through. |
| electric power | The rate at which electrical energy is converted to another form of energy. |
