Question

27] How can electrical energy be produced by
i] wind
ii] tidal waves?​

Answer 1

Electrical energy produced by

i} Wind : When the wind blows past a wind turbine, its blades capture the wind's kinetic energy and rotate, turning it into mechanical energy. This rotation turns an internal shaft connected to a gearbox, which increases the speed of rotation by a factor of 100. That spins a generator that produces electricity. And, The mechanical energy is then converted in electrical form of energy.

ii} Tidal Waves : Tidal waves are used to generate Tidal energy. Tidal energy is produced through the use of tidal energy generators. The large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity.And, The mechanical energy is then converted in electrical form of energy.
