Energy Engineering 2

Subject : engineering
Instructions:
  • Answer 34 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. The ratio of the useful energy delievered by a dynamic system to the energy supplied to it.






2. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms.






3. Changes one form of power to another.






4. Plant materials and animal waste used especially as a source of fuel.






5. Energy which a body possesses by virtue of bein in motion.






6. The unit of electric current in the meter- kilogram- second system of units. Referred to as amp or symbolized as A.






7. Any source of energy other than fossil fuels that is used for construcitive purposes






8. The use of heat from within the Earth or from the atmosphere near oceans.






9. The flow of electrical power or charge.






10. A closed electrical circuit in which the current is divided into two or more paths and then return via a common path to complete the circuit.






11. The net transfer of electric sharge (electron movement along a path) per unit of time.






12. The unit of electric resistance in the meter- kilogram- second system of units.






13. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air.






14. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body.






15. A system that links electicity produced in power stations to deliver it to where it is needed.






16. The state when objects are not yet in motion.






17. The rotating member of an electrical machine.






18. Changing one from of energy to another.






19. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit.

20. The unit of potential difference symbolized as V.






21. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress.






22. The potential difference measured in bolts. The amount of work to be done to move a charge from one point to another along an electric circuit.






23. A resource that can be replaced when needed.






24. An energy source that will never run out.






25. A result of a force moving an object a certain distance.






26. The opposition that a device or material offers to the flow of direct current.






27. The rate at which work is performed or energy is expended.






28. The production of electricity in conductors with the use of magnets.






29. A resource that cannot be replaced once used.






30. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.






31. Energy caused by the movement of electrons.






32. A dynamo or similar machine for converting mechanical energy into elctricity.






33. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work.






34. A circuit in which all parts are connected end ot end to provide a single path of current.
