Electrical Engineering XYZ MCQs
On which one of the following cycles does a modern steam power plants work:
- Bell – Coleman cycle
- Rankine cycle
- Carnot cycle
- Otto cycle
Correct answer: 2. Rankine cycle
Explanation: The Rankine cycle is the thermodynamic cycle upon which modern steam power plants operate. It’s a practical cycle used to convert heat into mechanical work through the expansion and compression of a working fluid (typically water or steam) in a system of turbines and pumps. This cycle is the basis for generating electricity in coal, oil, nuclear, and geothermal power plants.
