How Do Transformers Work?

How do transformers work? In a transformer, AC current in the primary winding creates a magnetic field in the core, inducing voltage in the secondary winding through electromagnetic induction. The turns ratio controls whether voltage is stepped up or down. How Do Transformers Work? They work on the principle of electromagnetic induction, where a varying magnetic field transfers energy between circuits. This allows voltage to be adjusted for efficient transmission, safe distribution, and the specific needs of different applications. For a deeper understanding of how these devices function in utility networks, see our detailed guide on utility transformers. …
