A transformer is an essential electrical device that transfers energy between circuits through electromagnetic induction. It plays a crucial role in voltage regulation, ensuring efficient power distribution across industries, households, and various infrastructures. In this article, we will explore transformers in detail, covering their working principle, types, key components, and real-life applications.
What is a Transformer?
A transformer is an electrical device that transfers electrical energy between two or more circuits using electromagnetic induction. It consists of two coils—primary and secondary windings—wrapped around a magnetic core. When an alternating current (AC) flows through the primary coil, it creates a changing magnetic field in the core, inducing a voltage in the secondary coil. This mechanism allows for voltage step-up or step-down, impedance matching, and electrical isolation.
