Question

How is energy converted in a hydroelectric plant?

The potential energy of water is converted to electrical energy when water flows past a generator.


The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy.


The kinetic energy of water is converted to electrical energy when water flows down the dam's channel and into the transformer.


The potential energy of water turns the generator's turbines, which results in the production of electrical energy.

Answer 1

Energy is converted in a hydroelectric plant as follows;

The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy

Step-by-step explanation:

The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine

The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;

The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.
