The windmill (wind turbine): When the blowing __________ strikes across the __________ of a windmill, it exerts a force on them due to which the blades of the windmill start _____________. This in turn rotates the shaft of the turbine and ___________ ___________.
Wind turbines are used to __________ electricity. The machines that generate electricity are the most conventional type with airfoil _____________ employing two to three tapered blades. Electricity can be produced by rotating an armature in between the poles of a strong ______________. The shaft of the armature of a generator is connected to the wind turbine by a connecting ________. When the wind rotates the blades of the wind turbine, the shaft rotates, and this in turn rotates the armature, thereby producing electricity.
