Basic Electricity Vocab

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A measuring device.






2. Shows relationship between Current - Voltage - Wattage and Resistance.

3. A material which can be magnetized - principally iron.






4. Meter used to measure resistance in an electrical circuit.






5. One millionth of an ohm.






6. The time rate at which work is done or energy is transferred. When a pressure of 1 volt sends a current of 1 ampere through a resistance of 1 ohm - the power in the circuit is said to be 1 watt.






7. A connection of circuit of low resistance. Current through each of the end- to- end devices is exactly the same. Only one path for the current.






8. A device which capacity is its chief electrical property; a device for storing or holding an electric charge; a capacitor.






9. Term applied to the loss of voltage in forcing current through any portion of a circuit. Different factors will cause a drop; material - size - (cross - sectional area) length - temperature.






10. Any of the spaces occupied by the orbits of a group of electrons of approximately equal energy surronding the nucleus of an atom.






11. Single NEGATIVE electrical charge. Orbits around the nucleus some in paths close to the nucleus - others in paths varying distance from the nucleus.






12. A circuit in which there is resistance (load) connected both in series and parallel.






13. An alternating current which current cycle begins earlier than its voltage cycle.






14. (Lode Stone) Certain type of mineral ore which has the natural Properties of a magnet.






15. A short circuit between two energized conductors and/or an energized conductor and a grounded phase. Very high current flow.

16. Transformer coil connected to the load. (Output side of a transformer regardless of voltage).






17. A circuit with only one path for current to flow. There are no branches.






18. In a battery - the electrode which takes up the electrons returning from the external circuit.






19. The space around a magnet in which the magnetic force is felt.






20. 1.Speed of conductors cutting lines of force 2.Strength of the magnetic field 3.Length of conductors cutting through the field






21. A unit of work or ENERGY. 1 kilowatt hour = 1 -000 watt hours






22. Opposition to current flow






23. The magnetism which a material retains after the magnetic force which magnetized it has been removed.






24. The liquid solution (sometime a paste) in which the electrodes are placed.






25. Fundamental constituents of matter. The 'elements' (tiny particles) which come together in various combinations to form molecules of many substances.






26. A current limiting device designed to melt and break the circuit when a specified current is exceeded. (The weakest point in a circuit)






27. Negative charge of electricity






28. Several secondary cells connected together for either a greater voltage or current output.






29. An instrument for measuring electric current






30. The unit of Electro- Motive Force






31. The moving part of a dynamo or motor consisting of coils of wire around an iron core.






32. A rate of movement of electrons through a conductor.






33. Those electrons in orbits farthest out from the nucleus - loosely bound and migrate from one atom to another.






34. One millionth of a volt.






35. 1.Material itself (Atomic Structure - Good conductor or Bad) 2.Length of the conductor 3.Cross - sectional area (Size) 4.Temperature






36. The opposite ends of a magnet where the magnetism is concentrated. Each magnet has two poles - designated as north and south.






37. A unit of power.






38. Coil connected to the source of power on a transformer.






39. Hardened steel which has been magnetized artificially and which retains its magnetic properties






40. That property of a material which determines how readily it conducts magnetic lines of flux. Opposite magnetic quality or conductivity.






41. A cell which is composed of certain materials which are used up during the process of delivering electric current.






42. A circuit with more than one path. Current branches to flow in every available path.






43. The voltage dissipation between any two points in a circuit. The voltage 'dropped' or 'dissipated' in forcing current through a resistance.






44. A generator that produces alternating current.






45. Certain quantity of electrons. The unit of measure that specifies the rate at which electric current flows per second.






46. Occurs when a stream of electrons are caused to move through a conductor.






47. Iron and certain alloys of iron which are magnetized by artificial means.






48. The unit of resistance. It is the resistance through which a voltage of 1 volt will produce a current of 1 ampere.






49. The part of the magnet where the magnetic force is most concentrated. Commonly referred to as the North or South pole or the positive or negative poles)






50. One million ohms.
