ELECTRICAL ENERGY

Electrical energy is a form of energy that is transported by an eléctrica current.


Electricity is very common for two reasons:
-It can be easily transformedinto other types of energy.
-It can be transported over long distances.


1.Electric power stations
A power station is a place where energy from natural resources is transformed into energy.
If the energy obtained is electricity, it is called an electric power station.


They use generators (alternators) to transform energy into electricity.

2.The transportation and distribution of electricity

• Raisin the voltage: it is raised to avoid the loss of energy as heat.
• High voltage lines:  are carefully planned and the lines are intalled on towers.
• Reducing the voltage: electrical substations are installed between high voltage lines and final consumers.
• Power is distributed: to homes, offices... The electric lines are usually suported by posts, and the voltage is reduced to very low ranges.
