Question

In a windmill:

• A. the translational motion of the windmill is used to turn the turbine of the electric generator.
• B. the rotatory motion of the windmill is used to turn the turbine of the electric generator.
• C. the upward motion of wind is the primary source of energy.
• D. slow winds are more efficient for energy production.

Answer 1

The correct option is B the rotatory motion of the windmill is used to turn the turbine of the electric generator.

Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
