Understanding Electric Energy: Circuits and Components

Electric energy is produced by the movement of electrons, forming the foundation of electricity. An electric circuit consists of a complete path for electron flow, distinguished by open and closed circuits. An open circuit lacks connectivity in some areas, preventing current flow, meaning electricity is off. Conversely, a closed circuit is fully connected, allowing current to flow freely, indicating electricity is on. Electric current refers to this constant flow. Materials play a vital role: conductors allow easy passage of electricity, while insulators resist it. Electromagnets, temporary magnets created by electric current, illustrate the practical application of these principles.

Presentation Transcript

  1. Electric Energy Notes

  2. Electric Energy (Electricity) • A form of energy that is produced when electrons move from one place to another.

  3. Electric Circuit • A complete path of conductors that electrons flow through

  4. Open Circuit • Circuit that is not connected in some area, so electrons do not flow through. Electricity is off.

  5. Open Circuit

  6. Closed Circuit • Complete circuit that allows electrons to flow through completely. Electricity is on.

  7. Closed Circuit

  8. Electric Current • The constant flow of electrons through a conductor

  9. Electric Conductor • A material that allows electricity to pass through easily.

  10. Electric Insulator • A material that does not allow electricity to pass through easily

  11. Electromagnet • A temporary magnet formed by passing an electric current through a wire coiled around an iron core
