  1. Electrical Vocabulary By Carlin Bright

  2. Electricity • The flow of electrons in a conductor

  3. Conductor • A material that permits the flow of electricity (like an electrical wire)

  4. Circuit • The complete path of an electric current

  5. Voltage • Pressure that forces current through a wire

  6. Volts • The SI unit for voltage

  7. Current • The volume of electrons flowing through the conductor

  8. Ampere • The base SI unit of electrical current

  9. Resistance • A way to measure the amount of work a component in a circuit can do. Something that is harder to run has more resistance.

  10. Ohm • The SI unit of electrical resistance

  11. Watt • One ampere under one volt of pressure (I×V)

  12. Service Drop • An electrical line running from a utility pole to a customer’s building or other premises

  13. Service Entrance • The fittings and conductors that bring electricity into the building

  14. Service Panel • The main distribution box that receives the electricity and distributes it to various points in the house through branch circuits.

  15. Conduit • Pipes or enclosed channels through which conductors are run

  16. Connectors • Secure connections between two or more conductors and conduit

  17. Electrical Wiring • Wires, boxes, and devices that control the distribution and use of electricity

  18. Circuit Breaker • A device for interrupting an electric circuit to prevent excessive current from damaging the equipment in the circuit or from causing a fire

  19. Fuse • A safety device that breaks the circuit when it is overloaded by melting a fusible link

  20. Switching • Controls the current to lights and appliances

  21. Receptacle • A contact device installed at an outlet for the connection of a portable lamp, appliance, or other electric device by means of a plug or a cord

  22. Lighting Outlet • An outlet designed to provide use of a lighting fixture

  23. Convenience Outlet • A device attached to a circuit to allow electricity to be drawn off for appliances or lighting
