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






2. One millionth of a volt.






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






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






5. Negative charge of electricity






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






7. 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.






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






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

10. The electrodes of a cell shaped as plates to expose a surface as possible to the electrolyte.






11. The unit of Electro- Motive Force






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






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






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






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






16. The number of cycles per second. Example: 60 cycles per second alternating current.






17. A rod or strip composed of two metals having different rates or coefficients of expansion. Upon being heated - it bends in a direction which causes the material with the greater rate of expansion to be on the outside.






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






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






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






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






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






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






24. A single electron or one of two or more electrons in the outer shell of an atom that is responsible for the chemical properties of an atom.






25. 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






26. One millionth of an ohm.






27. 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.






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






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






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






31. Total and complete opposition to the flow of electrons






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






33. 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.

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






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






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






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






38. 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.






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






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






41. Opposition to current flow






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






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






44. One- thousandth of a ampere






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