Question

The power generated in a windmill

• A. is more in the rainy season since damp air would mean more air mass hitting the blades
• B. depends on the height of the tower
• C. depends on wind velocity
• D. can be increased by planting tall trees close to the tower.

Answer 1

The correct option is C

depends on wind velocity

Power and Windmill.

1. Power- It is defined as the quantity of energy transported or converted per unit of time.
2. Windmill- It is a machine that generates electricity with the help of mechanical energy provided by wind.
3. Windmills convert the kinetic energy of wind into mechanical energy and then generate electricity with the help of generators.
4. The power generated by the windmill is directly proportional to the number of rotations of the blades of a windmill.
5. The number of rotations depends on the velocity of the wind.

Therefore, the power generated by the windmill depends on the velocity of the wind so the correct option is (C) depends on wind velocity.
