Electricity & Magnetism Vocabulary
| Term | Definition |
|---|---|
| Voltage difference | difference in electrical potential between two points |
| Parallel circuit | has two or more pathways for electricity to flow |
| Resistance | Tendency to oppose the flow of electrical current |
| Circuit | pathway for electrons to follow |
| Static electricity | an imbalance of electric charges on the surface of an object |
| Ohm's Law | formula used to calculate the relationship between voltage, current, and resistance in an electrical circuit |
| Conductor | material that allows the flow of electrons to move easily |
| Electric field | area around charged particle which a force would be exerted on other charged particles |
| Electric power | the rate at which electrical energy is transferred by an electric circuit |
| Kilowatt-hour | a measure of how much energy is being used |
| Charging by contact | giving an object a charge by placing it in contact with another charged object |
| Charging by induction | a charged object is brought close but does not touch conductor |
| Electrical current | the constant flow of electrons from one atom to another |
| Insulator | material that does not allow electrons to move easily |
| Law of Conservation of Charge | States that electric charge can neither be created or destroyed but only be transferred from object to another |
| Series Circuit | current has only one pathway for electricity to flow |
