In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any co
AI overview
A transformer is an electrical device that transfers energy between separate circuits using changing magnetic fields, without requiring a direct connection between them. Transformers matter because they enable efficient power distribution and allow voltage levels to be adjusted for different applications, making modern electrical systems practical.
