Question

Which energy of water is used to produce hydroelectricity?

• A. Potential energy
• B. Kinetic energy
• C. Both a and b
• D. None of these

Answer 1

The correct option is C Both a and b

When water is stored at a height it has potential energy in it. When this water is allowed to flow down from a height potential energy of water gets converted into kinetic energy. A hydraulic turbine converts the energy of this flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity. The operation of a generator is based on the principles discovered by Faraday.

So, the correct answer is 'Both a and b'.
