Electricity and Circuits vocab
| Term | Definition |
|---|---|
| Circuit | Complete path around which current can flow. Has the following required components: voltage source, path, and load. |
| Series Circuit | A circuit in which electrons have only one path back to the source. There are no branches. |
| Parallel Circuit | A circuit that has branches and junctions. |
| Current | The rate of flow of electrons. |
| Resistance | A device that restricts the flow of electrons in a circuit. |
| Ohm | Unit for electrical resistance. |
| Ampere | Unit for electrical current. Equivalent to Coulombs/s. |
| Schematic Diagram | A circuit drawing that uses recognizable symbols to represent circuit components. |
| Watt | Unit for power. Equivalent to Joule/s. |
| Voltage | Potential Difference in a circuit also known as the electromotive force (emf). |
| Voltmeter | Instrument used to measure voltage in a circuit. |
| Ammeter | Instrument used to measure current in a circuit. |
| Direct Current | A continuous electric current that flows in one direction only. |
| Alternating Current | An electric current that changes direction at regular intervals. |
