In a bydel station, the motion produced in tur bines is due to the

Options

A. burning of coal
B. burning of diesel
C. flow of water
D. production of steam

Explanation

**Step-by-Step Solution:**

1. **Understanding Hydel Stations:**
- A hydel station, also known as a hydropower plant, generates electricity by using the energy of flowing or falling water.

2. **Components of a Hydel Station:**
- The main components include a dam, turbines, and generators (dynamos). The dam stores water, creating a potential energy source.

3. **Mechanism of Energy Conversion:**
- When water is released from the dam, it flows down due to gravity. This flow of water has kinetic energy.

4. **Turbine Function:**
- The flowing water strikes the blades of the turbine, causing it to spin. The motion of the turbine is directly related to the flow of water.

5. **Electricity Generation:**
- The spinning turbine is connected to a generator (dynamo). As the turbine rotates, it turns the generator, converting mechanical energy into electrical energy.

6. **Analyzing the Options:**
- The question provides four options:
1. Burning of Coal
2. Burning of Diesel
3. Flow of Water
4. Production of Steam
- We need to identify which option is responsible for the motion of the turbines in a hydel station.

7. **Evaluating Each Option:**
- **Burning of Coal:** Incorrect, as coal is not used in hydel stations.
- **Burning of Diesel:** Incorrect, as diesel is not used in hydel stations.
- **Flow of Water:** Correct, as the kinetic energy from the flowing water causes the turbines to rotate.
- **Production of Steam:** Incorrect, as steam production is not involved in the operation of a hydel station.

8. **Conclusion:**
- The correct answer is **Flow of Water**, as it is the kinetic energy from the flowing water that produces motion in the turbines.
