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. The property of a material that opposes the flow of current.






2. The unit of Electro- Motive Force






3. One- thousandth of a ampere






4. An instrument for measuring electromotive force in volts. It must be connected across the load that causes the votage drop.






5. A very low resistance path placed in a circuit in such a manner as to allow an excessive current flow.






6. Negative charge of electricity






7. Any device which may be placed in the circuit and which offers opposition to the flow of electrons around the circuit.






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






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






10. The center portion of an atom which has a positive electrical charge.






11. A material which CANNOT be magnetized. Example: Wood - Glass - Brass - Rubber...






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






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






14. A generator that produces alternating current.






15. The process of producing an electromotive force in a conductor as a result of the cutting of magnetic lines of force by a conductor.






16. One millionth of a volt.






17. Smallest part a substance can physically divided into composed of 2 or more atoms.






18. A circuit carrying three alternating currents whose cycles begin one after another. 120 electrical degrees apart.






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






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






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






22. A circuit with two or more paths for the current to take.






23. Opposition to current flow






24. One million ohms.






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






26. A certain force exhibited by some materials which give them the ability to attract other materials. Principally iron or its alloys.






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






28. An instrument for measuring electrical power. Most common use: The meter of your house to measure electrical consumption.






29. The area surrounding a magnet in which magnetic properties are exhibited






30. An instrument for measuring electric current






31. The dissimilar metals which are placed in an electrolyte to form a cell.






32. The difference between the electrical condition of one point in an electric circuit and that of another point which tends to cause current to flow between two points. Measured in volts.






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






34. Rate of electrons flow (current flow). When one 'Coulomb' of electrons pass a given point in one second.






35. 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.






36. An alternating current which current cycle begins later that its voltage cycle.






37. A resistor designed so that its resistance is readily adjusted.






38. The condition where the free electrons are caused to move in the same direction along or through a conductor.






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






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

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






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






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






44. Electric charges at rest. Caused by friction of materials - where a surplus of electrons exists and may be discharged.






45. A current which reverses in direction at regularly recurring intervals - the total flow in one direction being equal to that in the other direction.






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






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

48. A measuring device.






49. A complete path provided for the flow of electrons. Consists of a source - with a closed conducting path leading from the source and back to the source






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