Although you may think you know all there is to know about transformers, the truth is, you might be surprised.

If you’ve wondered, how does a transformer work? Perhaps it’s time you were filled in on this integral part of our society.

Transformers are a crucial part of how our electrical power distribution system works. You’ll be surprised to learn how far their reach extends into our day-to-day lives.

From producing the electricity that lights our light bulbs to changing energy sources, our reliance on transformers never seems to end. Continue reading to learn more!

What is a transformer?

A transformer is a static electrical device that transfers energy between two or more circuits through electromagnetic induction.

A changing current in the primary winding creates a magnetic field in the transformer’s core. This core induces a voltage in the secondary winding.

This voltage is proportional to the number of turns in the secondary winding and is inversely proportional to the number of turns in the primary winding. The transformer’s purpose is to change the voltage in an electrical circuit.

How Does a Transformer Work


A transformer is a device that transfers electrical energy between two or more circuits through inductively coupled conductors, which are the transformer’s coils. A varying current in one coil of the transformer produces a varying magnetic flux in the transformer’s core, which induces a varying electromotive force across a second coil wound around the same core.

Electrical energy can be transferred between the two coils, without a metallic connection between them, as long as they are close enough to couple magnetically.

The transformer increases and decreases voltage by varying the number of turns in the primary and secondary coils. The primary coil has more turns than the secondary coil, which means that the secondary coil has more voltage than the primary coil.

The transformer can increase the voltage by adding more turns to the secondary coil or adding more coils to the secondary coil. The transformer can decrease voltage by decreasing the number of turns in the primary coil or adding more coils to the primary coil.

The Advantages and Disadvantages of Transformers

Disadvantages of Transformers

What some transformer benefits you may ask. Transformers are very efficient, with very little power loss. They are also very reliable and can last for many years with proper maintenance.

Transformers can be expensive. They can also be bulky and heavy. Additionally, they require a steady supply of electricity to work properly, which can be a problem in areas with unreliable power grids. If you need to repair a transformer near you, be sure to contact

Understanding Transformers

So how does a transformer work? Again, transformers convert alternating current (AC) to direct current (DC), or vice versa. AC to DC conversion is used in a variety of devices, such as computers, televisions, and radios. DC to AC conversion is used in devices such as power plants and electric motors. Now that you know the basics of how transformers work, you can dive deeper into the amazing world of electronics.
