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






2. Changes one form of power to another.






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






4. 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.






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






6. Changing one from of energy to another.






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

17. An energy source that will never run out.






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






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






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






21. The flow of electrical power or charge.






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






24. Energy caused by the movement of electrons.






25. 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.






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






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






28. The ratio of the useful energy delievered by a dynamic system to the energy supplied to it.






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






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






31. A resource that can be replaced when needed.






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






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






34. 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.
