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. CSA ~LINK~






2. The part of a circuit that supplies power to the entire circuit or part of the circuit. Usually a separate unit that supplies power to a specific part of the circuit in a system.






3. Inspection - analysis and action required to ensure quality of output.






4. A coil of wire wound about a magnetic material - such as iron - that produces a magnetic field when current flows through the wire.






5. An electrical resistor composed of semiconductor material - whose resistance is a known rapidly varying function of temperature.






6. An ionized gas containing about equal numbers of positive and negative charges - which is a good conductor of electricity - and is affected by a magnetic field.






7. The behavior of charged particles and the steady motion of charge in magnetic and electric fields.






8. A meter used to measure units of volts.






9. Chemical changes and energy produced by electric currents.






10. A form of silicone dioxide. Commonly used in the making of radio transmitters and heat resistant products.






11. A form of energy produced by the flow of particles of matter and consists of commonly attractive positively (protons [+]) and negatively (electrons [-]) charged atomic particles. A stream of electrons - or an electric current.






12. The standard that is used to make comparison measurements or calibrations.






13. Radio Frequency Interference.






14. An anode (+) or cathode (-) conductor on a device through which an electric current passes.






15. The rate at which electricity flows - measured in amperes - 1 ampere = 1 coulomb per second.






16. A device that converts AC voltage to pulsating DC voltage.






17. Silicone Controlled Rectifier.






18. Symbol used to denote transmitter.






19. One millionth of an amp.






20. The act of the opening of an electrical circuit.






21. Resistance Temperature Detector.






22. A circuit which may have one or many resistors and/or other various devices connected in a series so that the current has only one path to follow.






23. An electrical circuit that is not 'made'. Contacts - switches or similar devices are open and preventing the floe of current.






24. A device used to store electrical energy in an electrostatic field until discharge.






25. The method by which two devices or systems are connected and interact with each other.






26. The speed or time rate of change of displacement.






27. Pressure that is less than atmospheric pressure.






28. A silicone semiconductor that maintains a fixed voltage in a circuit.






29. IBEW;






30. The time delay between the output signal and the response time of the receiver of the signal.






31. The unit of power. One watt equals one joule per second - 1/746th horsepower.






32. A sudden and unwanted increase or decrease of supply voltage or current.






33. A positive (+) electrode. The point where electrons exit from a device to the external electric circuit.






34. A high-intensity incandescent lamp with a quartz bulb containing an inert gas of iodine or bromine vapor.






35. One millionth of a meter.






36. A variable resistor.






37. Normally Open.






38. A unit of electrical current named after French physicist Andr






39. The adjustment of a display that results are zero on the display corresponding to a non-zero signal.






40. An interconnected arrangement of parts for carrying high-voltage electricity.






41. ISA;






42. Variable Frequency.






43. Ultra High Frequency






44. A three mode control consisting of time Proportioning - Integral and Derivative rate action.






45. When there is current through a semiconductor p-n junction it is the resistance of a forward-biased junction.






46. Symbol used to denote transformer.






47. A full-wave rectifier where the diodes are connected in a bridge circuit. This allows the current to the load during both the positive and negative alternating of the supply voltage.






48. A highly accurate bridge configuration that is used to measure three-wire RTD thermometers.






49. Electric and magnetic force field that surrounds a moving electric charge.






50. The time based relationship between a reference and a periodic function.
