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 material that has many free electrons thus allowing electric current to flow through it easily.






2. Invisible lines along which magnetic energy travels from one pole of a magnet to the other.






3. 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.






4. 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.






5. 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.






6. A unit of power; equal to 550 foot- pounds per second of approximately 746 watts.






7. A transformer designed to raise the voltage of an alternating current. Most common use; In a generating plant to raise the voltage.






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






9. One million ohms.






10. A coil of wire designed to act as a magnet as a result of carrying an electrical current. It is usually wound on a soft iron core.






11. A measuring device.






12. 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)






13. One- thousandth of volt.






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






15. Lines representing the direction of the magnetic force in a magnetic field.






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






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






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






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






20. One millionth of an ampere.






21. A transformer designed to lower voltage of an alternating current. Most common type of transformer used on a power system.






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






23. Opposition to current flow






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






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






26. Those electrons in orbit nearest the nucleus - not easily dislodged from their normal orbits.






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






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






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






30. The unit of electromotive force - potential - pressure - or voltage which produces a current of one ampere in a circuit having a resistance of 1 ohm. This is the force created to move electrons through a circuit.






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






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






33. Negative charge of electricity






34. A generator that produces alternating current.






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






36. A machine which utilizes magnetism to produce an EMF and consequently - an electric circuit.






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






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






39. A cell which is rechargeable. Uses materials which change in compostition during delivery of current - but may be restored to original condition upon recharge.






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






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






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






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






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






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

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






47. A material with few free electrons. A structure or material used to prevent the passage of current.






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