An O-core transformer consisting of two coils of copper wire wrapped around a magnetic core. In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.
May 9, 2024 · A transformer is defined as a passive electrical device that transfers electrical energy from one circuit to another through the process of electromagnetic induction. It is most commonly used to increase (‘step up’) or decrease (‘step down’) voltage levels between circuits.
The transformer is basically a voltage control device that is used widely in the distribution and transmission of alternating current power. The idea of a transformer was first discussed by Michael Faraday in the year 1831 and was carried forward by many other prominent science scholars.

- A transformer is a device used for stepping up or stepping down AC voltages.
- A step-up transformer is one for which the output voltage is greater than the input voltage.
- A step-down transformer is one for which the output voltage is less than the input voltage.
- The turns ratio of a transformer is the ratio of the number of turns in the secondary to that of the primary.
