How Does Electrical Transformers Works?


Have you ever walked on the countryside and noticed the tangling power lines hanging on the sky and intermediately connected electrical transformers? They are responsible in carrying electricity with high amount of voltage that originated from power plants. All of these are intended to supply homes. Do not get this wrong because a household is most likely to utilize a smaller voltage of electricity. It would only need around 250 volts. In order to reduce high voltage, electrical transformers come to place. This equipment goes with electromagnetic energy. What else can be expected from this?

The Mechanism of an Electrical Transformer


There is only a plain logic that applies to the way an electricity works. The moment a fluctuating electric current runs through a wire, a magnetic field is generated. This will go around. As a matter of fact, an invisible pattern may be formed. This is referred to as magnetism.1 (2) The electric current is responsible in determining what the strength of the magnetism is. This means that if there is bigger current, there will be a way stronger magnetic field. This is fascinating about electricity. The said electric current will be generated because of the fluctuation of the magnetic field. This means that when a coil of wire is placed, an electric current will be sent back to the first coil. This will then lead to the creation of the electric current towards the second wire. The first coil current is called primary current. The one that follows is secondary current. Electromagnetic conduction is the one that passes through an empty space.

Transformers at home

In most cities and towns, huge transformers are always stumbled upon. They are of high-voltage and usually, they still have to be converted prior to supplying. Apart from this though, transformers are also seen in homes. Reliable appliances such as dishwashers and washing machines utilize 110 to 240 volts. Electronic devices on the other hand like computers, laptops, mobile cellphones and MP3 players only consume tiny voltages. For instance, a laptop would only need 15volts to operate. The battery of iPod would only handle only 6 volts. When charged, it would ask for 12 volts. Learn more here,

The aforementioned occurs because the electronic appliances are equipped with small transformers in them. They are only mounted at the power lead. This would convert 110-240 volt of domestic supply. This is why the number of voltage is made even way smaller. So no one should wonder about the bulky power cords of these cellphones anymore. They always have transformers in them!


A tenfold of home transformers are intended for rechargeable batteries to charge up. The plain logic goes here too. The electricity would flow in the transformer coming from the outlet wall would be changed into lower voltage. This would directly go to the phone or iPhone battery. There are also other kinds of transformers which are seen in electric toothbrush. However, the difference is that they do not have any power lead in them. They are related to induction chargers.
