Electrical energy

It is a form of energy that is transported by an electrical current. Electricity is the most useful in the world for two reasons:

-It can be transformed into other types of energy so better than others.
-It can be transported over long distances cheapest and more efficient.

ELECTRIC POWER STATIONS.
A power station is a place when energy from natural resources is transfromed in the energy that we may use. Depends of the energy we will generate , recives a name or another.
How the electricity is generated?

If we want transform the energy into electricity, we usegenerators and if generators are used in power stations ,are called alternators. An alternator is make up by a stator and a rotor. The rotor has an even numbers of coils that receive direct current. They produce an electromagnetic field . Aturbine turns the axis of the rotor and generate electric current. This system is used at all power stations except for photovoltaic stations.
