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 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.






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






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






4. Total and complete opposition to the flow of electrons






5. 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.






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






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






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






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






10. In an electrical circuit - or part of an electric circuit - the intensity of the current is equal to the electromotive force that drives it divided by the resistance of the circuit.

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






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






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






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






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






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






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






18. A measuring device.






19. A device used to change the voltage of an alternating current circuit.






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






21. One millionth of an ampere.






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






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






24. (EMF) The force created by an electric generator (or by other means) which causes current to flow. (Same as Voltage - Volts - Electric Potential - Pressure).






25. Positive charge of electricity. Located in the nucleus of the atom.






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






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

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






29. One millionth of a volt.






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






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






32. The complete path through which the lines of force travel - leaving the north pole and re- entering the south pole.






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






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






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






36. The unit of Electro- Motive Force






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






38. A unit of power.






39. A generator that produces alternating current.






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






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






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






43. The path of an electric current. To permit a steady flow of current - the path must be complete. Commonly - a complete circuit includes a device for the production of an electromotive force - connecting wires - and a device supplied with electricity.






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






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






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






47. 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






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






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






50. 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)
