OR
Explain how an energy source, a turbine and a generator are used to produce electric energy.

Explanation

(i) Electricity is generated at a power atation using an energy source , a turbine and a generator.
(ii) The energy souce is used to drive the turbine.
(iii) A turbine has blades. A flow of liquid or gas is directed on these bledes of the rurbine , which causes them to rotate.
(iv) The turbine which in turn is connected to an electric generator causes the magnet in the electric generator causes the magnet in the electric generator causes the magnet in the electric generator to rotate and electric energy is produced.
