प्रश्न
Explain the principle of working of the windmill for generating electricity.
उत्तर
It works on the principle of conversion of the kinetic energy of blowing wind into electrical energy. When the blowing wind strikes across the blades of a windmill it exerts a force that rotates its blade. The turning of the blades would simultaneously cause the shaft to turn, which is connected to a generator. This makes the generator produce electricity.
