How Electricity Travels.

Have you ever wondered how electricity travels? These days we have electricity to power our homes and cities, and to survive. If we didn’t have electricity, we wouldn’t have televisions, computers, or appliances. We would also not be able like use the internet, watch the news, or use the oven.

The first thing that makes the electricity, is a place called a “Power station”. The power station have many generators, which produces the electricity. Did you know that the generator is made out of metal, which is a good conductor? Insulators are the opposite of conductors, which stops electricity from going. Rubber and glass are very good insulators.

When it is out of the power station, the electricity travels through the pylons. Pylons are more bigger than ordinary power lines, because they produce more electricity. Are you aware that pylons generate electricity from other power stations, and sometimes, there are pylons in the streets.

When the electricity travels from the pylons, electricity travels on to a substation. Another word for substation is transformer, although, they don’t have the same size. Some substations have wires that go underground, which are covered with pipes, so it doesn’t electrocute anyone.

Later on, the electricity travels through power lines (or distribution lines), which is more smaller than pylons. Distribution lines let electricity go through to houses. Some houses have power lines underneath the ground. Finally, the electricity arrives to the houses for the appliances to work.
