What is a transformer and how does it work?
A transformer is an essential device in electrical engineering, widely used to transfer electrical energy between two or more circuits through electromagnetic induction. By changing voltage levels, transformers enable safe power transmission across vast distances, making them vital in power grids and various electrical devices. This article provides a detailed explanation of how transformers work, including their principles, types, and applications. Table of Contents Introduction Basics of Transformers Working Principle Transformer Equations Types of Transformers Applications of Transformers Conclusion FAQ Basics of Transformers A transformer consists of primary and secondary coils (windings) and a magnetic core. The primary winding connects to the power source, while the secondary winding connects to the load. When alternating current (AC) flows through the primary coil, it generates a magnetic field, which induces a voltage in the secondary coil due to Faraday’s
