Answer:
a) potential energy to kinetic energy
b) kinetic energy to mechanical energy
c) mechanical energy to electrical energy
Step-by-step explanation:
In the hydroelectric power plant, following energy conversions take place -
a) When water falls from great heights , its potential energy is converted to kinetic energy
b) When fast moving water turns the blade of turbine, then its kinetic energy is converted into mechanical energy
c) When the rotating turbine rotate the Electromagnetic coil of generator, the mechanical energy is converted into electrical energy.
