Question

describe how hydro energy can be converted into electrical energy . write any two limitation of hyro energy

Answer 1

when water is allowed to fall on the blades of a turbine from a height or with force it causes the blades to move which generated EMF in the turbine and if the circuit is closed a current is induced .this is how it converts potential energy into electric energy.
limitations are
a) the cost of setting up a hydro powerplant is very high(although successive costs are low)
b)there is still not much use of hydropowerplants in some places due to lack of sufficient water or in landlocked countries

Answer 2

Answer:

hope it helps

_________________________________________________________

In hydropower plants, a large amount of water is stored at a height. This stored water is then allowed to fall on rotating turbines. The force of the running water (kinetic energy of running water) causes the turbines of the plant to spin. The rotating turbines then spin the generator, which ultimately produces electricity. In this manner, the kinetic energy of the running water is converted into mechanical energy and then finally into electrical energy.

Two limitations of Hydropower Energy are:

Causes a change in the course of rivers and lot of land is submerged under water.

Fish and wildlife are affected drastically.
