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. Pounds per square inch gage. Pressure in relationship to the ambient air pressure>






2. The basic of thermal energy. The work done by the force of one newton acting through a distance of one meter.






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






4. A fundamental negatively (-) charged atomic particle that rotates around a positively (+) charged nucleus of the atom.






5. Ultra High Frequency






6. A fluctuation in the intensity of a steady current.






7. A unit of energy in solid-state physics with mass and momentum but that does not exist as a free particle.






8. 'British Thermal Unit' - the amount of thermal energy required to raise one pound of water 1degree F. One BTU is equal to .293 watt hours. One kWh is equal to 3412 BTUs.






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






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






11. Silicone Controlled Rectifier.






12. IBEW;






13. A unit of electric charge. The amount of charge conveyed in one second by one ampere.






14. The unit for capacitance. A capacitor that stored one coulomb of charge with one volt across it will have a value of one farad.






15. One thousandth of an inch.






16. 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.






17. A hypothetical nuclear of a quark plus an antiproton.






18. Intensity. The commonly used symbol used to represent Amperes when used in formulas. I = Intensity = Current = Amps = Amperes.






19. OSHA;






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






21. Kva; One thousand volt amps.






22. The rate of transfer of energy.






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






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






25. The electrical demand of a process. Load can be expressed or calculated as amps (current) - ohms (resistance) or watts (power).






26. Symbol used to denote transformer.






27. The magnitude and time phase of a quantity - represented by a plotted line.






28. 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.






29. MV; One thousandth of a volt. The difference in potential needed to cause a current of one milliampere flow through a resistance of one ohm.






30. Symbol for Mega - one million.






31. The range of temperature over which a device may be safely used. The temperature range which the device has been designed to operate.






32. 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.






33. Kwh; One thousand watt-hours.






34. A variable resistor.






35. The energy delivered by a circuit or device. The electrical signal produced by the input to the transducer.






36. A rise and fall of voltage - current - or other faction that would be constant under normal conditions. A pulse that is intentionally induced will have a finite duration time.






37. European environmental ratings. Similar to NEMA ratings in the USA. IP;*site has NEMA comparisons ~LINK~






38. (ampere)The basic unit of current in an electrical circuit. One ampere is the rate of flow of electric current when one coulomb of charge flows past a point in the circuit in one second. Symbolically characterized by the letter 'I' and sometimes 'A'






39. One millionth of a meter.






40. A circuit conductor that is grounded to become part of the electric circuit by design and intent.






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






42. 'American Wire Gauge' system used to determine wire size.






43. The form of radiation used to make non-contact temperature measurements. In the electromagnetic spectrum it is the area beyond red light from 760 nanometers to 1000 microns.






44. kV; One thousand volts.






45. The amount of time it takes for a device to react to an input signal.
