Electrical Components

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. ANSI;






2. A hypothetical basic subatomic nuclear particle believed to be the basic component of protons - neutrons - etc.






3. The resistance to electrical current. Resistance is measured in ohms.






4. A process that is kept at a constant temperature.






5. Mm; One thousandth of a meter.






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






7. One millionth of an amp.






8. IEEE;






9. 'Common Mode Voltage.' The voltage which is tolerable between signal and ground.






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






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






12. A reference point at zero potential with respect to the earth. In an electronic circuit it is the common return path for electric current. A conducting connection between the earth and an electrical circuit or electrical equipment. Also - the negativ






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






14. Kw; One thousand watts.






15. The amount of heat needed to convert one pound of water to one pound of steam. Latent heat is expressed in BTU per pound.






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






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






18. A variable resistor.






19. A connected path to earth or to a conductive body that has a reference potential to earth.






20. The opposition to electrical flow.






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






22. The average temperature of a process.






23. Expressed in webers - it is the product of the average normal component of the magnetic intensity over a surface and the area of that surface.






24. 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.






25. SI; The standard metric system of units.






26. A tube - pipe or trough that carries and protects electric wiring.






27. The delayed period of time when outputs are turned off when power is initially applied.






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






29. Radio Frequency Interference.






30. kV; One thousand volts.






31. EPA; ~LINK~






32. OSHA;






33. The element inside a vacuum tube - incandescent lamp or other similar device.






34. A device that transfers power or energy from one system to another - such as taking a physical quality and changing it to an electrical signal.






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






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






37. -459.67






38. The rapid on/off cycling of a relay caused by improper signal or adjustment - faulty contacts - or other malfunction.






39. One millionth of a volt.






40. NEMA;






41. The unit by which electrical resistance is measured. One ohm is equal to the current of one ampere which will flow when a voltage of one volt is applied






42. A switch in a controller that manually resets after exceeding the controllers limit.






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






44. A circuit element or components that allows signals of certain frequencies to pass and blocks signals of other frequencies.






45. Normally Closed.






46. One of the very small discrete packets into which many forms of energy are subdivided.






47. The conductor that is used by intent to connect the grounded circuit of an electrical wiring system or equipment to a grounding electrode with reference to earth.






48. One thousandth of an inch.






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






50. Pounds per square inch differential. The difference in pressure between two points.
