Everything about Transformer
Device to couple energy between circuits
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 coil due to a changing magnetic flux encircled by the coil. Wikipedia →

📖 Definitions
Noun Something that transforms, changing its own or another thing's shape.
Noun A static device that transfers electric energy from one circuit to another by magnetic coupling; primarily used to transfer energy between different voltage levels, which allows the most appropriate voltages for power generation, transmission and distribution to be chosen separately.
Noun A neural network architecture composed of layers of attention which takes sequences of tokens (representing text, images, audio, or other modalities) as input.
Noun Alternative letter-case form of Transformer.
