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






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






3. The rotating member of an electrical machine.






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






5. 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.

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






7. 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.






8. A unit of power.






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






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






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






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






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






14. A measuring device.






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






16. A complete sequence of events - as an alternating- current cycle.






17. 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.






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

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






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






21. Single POSITIVE electrical charge - located in the middle of an atom.






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






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






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






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






26. 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.






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






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






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






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






31. Total and complete opposition to the flow of electrons






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






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






34. One- thousandth of a ampere






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






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






37. 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.






38. One millionth of a volt.






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






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






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






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






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






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






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






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






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






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






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






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