A stationary induction apparatus to change electrical energy at one voltage and current to electrical energy at another voltage and current through the medium of magnetic energy, without mechanical motion.
Introducing an electrical apparatus capable of modifying voltage levels exclusively in alternating current systems. This particular device, known as a transformer, comprises multiple cells intricately linked through magnetic induction. Its primary function involves the transfer of electric energy between one or more circuits, while maintaining the frequency unchanged. However, it accomplishes this transfer with modified values of voltage and current.
