Electrical Engineering XYZ MCQs
Which of following power plants normally operate at high speeds:
- Diesel engine
- Hydro electric
- Petrol engine
- Steam turbine plants
Correct answer: 4. Steam turbine plants
Explanation: Steam turbine plants, on the other hand, often operate at very high speeds. They use steam to drive turbine blades, and these turbines can rotate at extremely high RPMs, often in the thousands. Steam turbines are commonly used in power generation because they can efficiently convert thermal energy into mechanical energy, which is then used to generate electricity. The high speeds at which steam turbines operate make them suitable for large-scale power generation.
