How Transformers Step-Down or Step-Up Voltages

An electric transformer is a device that is used to transfer electrical energy from one circuit to another circuit through electromagnetic induction. The transformer is made up of two coils of wire, called the primary coil and the secondary coil, which are wound around a core made of magnetic material.

What Do the Coils/Windings Do?

When an alternating current (AC) flows through the primary coil, it creates a magnetic field that varies with the frequency of the AC. This magnetic field then induces a voltage in the secondary coil. Which is proportional to the number of turns in the coil and the rate of change of the magnetic field.

The voltage induced in the secondary coil can be either higher or lower than the voltage applied to the primary coil, depending on the ratio of the number of turns in the primary and secondary coils. If the secondary coil has more turns than the primary coil, the voltage in the secondary coil will be higher than the voltage in the primary coil. That setup would be called a step-up transformer. If the secondary coil has fewer turns than the primary coil, the voltage in the secondary coil will be lower than the voltage in the primary coil. It would then be called a step-down transformer.

Conclusion

The transformer is a very efficient device, with very little energy lost as heat or other forms of energy. This makes it an important component of the electrical power distribution system, where it is used to step up or step down the voltage of the power supply to levels suitable for transmission and distribution.
