what is electrical energy? how electricity is generated in the following?
a hydroelectric power plant
b windmill power plant
c Solar Plant
Answers
Answer:
Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.
Explanation:
please drop some thanks for me and mark me as brainliest
(a) The energy in charged particles is called electrical energy. Flow of water is used for moving the turbine. Turbine converts kinetic energy into electric energy.
(b) Blades of windmill move due to wind speed. Fan of windmill is attached to a turbine. Turbine converts kinetic energy into electric energy.
(c) Solar energy plant uses two methods to produce electricity. In one method, photovoltaic cells convert heat energy into electric energy. In another method, water is converted into steam by using heat energy. Steam is then utilized to turn the turbines and electricity is produced.
