A transformer is an electrical device that transfers energy between circuits through electromagnetic induction. It consists of coils wrapped around a core and is used to change voltage levels. In this article, we are going to learn about transformers in detail, including their function, types, components, and applications across various sectors.
What Are Transformers?
Transformers are a type of electrical device that transfers electrical energy between circuits using electromagnetic induction. They consist of two or more coils of wire wrapped around a magnetic core.
When an alternating current passes through one coil (the primary), it induces a changing magnetic field in the core, which in turn induces a voltage in the other coil (the secondary). This allows for voltage transformation, isolation, and impedance matching in electrical systems.
