Vocabulary List
| Question | Answer |
|---|---|
| Electromagnetism | The relationship between electricity and magnetism, where an electric current produces a field. |
| Electromagnets | A temporary magnet created by coiling a wire around a metal core, and passing a current through a wire. |
| Electric Motors | A device which converts electricity to mechanical energy. |
| Electric Generator | A device that converts mechanical energy to electrical energy. |
| Electric Energy | A form of energy that is produced when electrons move from one place to another |
| Electric Current | A complete path of conductors that electrons flow through |
| Electric Conductor | Metal wires commonly used to move electrical current through a circuit |
| Electric Insulator | The wires in a circuit are covered in an electric insulator. This is a material that does not allow electricity to pass through. |
| Fuses and Circuit Breakers | Fuses and circuit breakers are used to stop the flow of electricity if the current becomes too strong. These safety devices are common in houses, buildings, and automobiles. |
| Open Circuits | An open circuit is not connected in some area, there are no potential differences, so electrons dont flow. Electricity is off. |
| Closed Circuit | In a closed circuit electrons flow because there is a potential difference. Electricity is on. |
| Electric Current | The constant flow of electrons through a conductor |
| Alternating Current | Currents flow back and forth in a circuit. It is the type of current that flows into homes and businessess. |
| Direct Current | Current flows in one direction in a circuit. This type of flow is associated with batteries. |
| Series Circuits | Characterized by only having a single path for electrons to flow. A major drawback to this circuit is that if there is a break in the circuit electricity quits flowing. |
| Parallel Circuits | Characterized by having multiple pathways for electrons to flow. Even if one bulb/load burns out the others continued to receive flow of electrons. |
| Ohms Law | The relationship between voltage, current, and resistance |
| Voltage | Measured in volts, symbolized by the letter "V" |
| Current | Measures in amps, symbolized by the letter "I" |
| Resistance | Measures in ohms, symbolized by the letter "R" |
