A transformer is a fundamental passive component in electrical engineering designed to transfer energy between circuits through electromagnetic induction. By utilizing a magnetic core and multiple wire coils, these devices can efficiently increase or decrease voltage levels for various power and signal applications. The provided text outlines the physical principles governing their operation, such as Faraday's law, while also detailing common energy losses like hysteresis and eddy currents. It further explores various construction methods, including laminated steel, toroidal, and air cores, alongside essential cooling and insulation techniques. Historically, the technology evolved from early 19th-century discoveries by Faraday and Henry into the sophisticated closed-core systems that now underpin global alternating current distribution. Today, transformers remain indispensable across the electrical grid, appearing in everything from massive substation units to tiny electronic components.
