In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.

Feb 24, 2012 · A transformer is defined as a passive electrical device that transfers electrical energy from one circuit to another through the process of electromagnetic induction.

May 22, 2026 · A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the …

⚡ Quick Answer A transformer works by electromagnetic induction. AC in the primary coil creates a changing magnetic field, which induces a voltage in the secondary coil. The voltage ratio equals the …

Jun 5, 2020 · A transformer is an electrical device designed to transfer electrical energy from one circuit to another at the same frequency. It is also referred to as a static machine since it does not have any …

The main purpose of a transformer is to adjust the voltage levels up or down between two circuits without changing the frequency, which makes controlling and delivering power much easier and …

What is a Transformer? In the simplest of terms, a transformer is an electrical device that takes a given input voltage and changes it to a different output voltage. This change can either be an increase or a …

1 day ago · In a transformer, when alternating current (AC) flows through the primary winding, it produces a continuously changing magnetic flux around the coil. This magnetic field passes through …

Nov 17, 2025 · A transformer is a static electrical device that transfers energy between circuits using electromagnetic induction. It changes AC voltage levels (step-up or step-down) while maintaining the …

Sep 30, 2025 · Transformer is the device for setting electrical energy between two or more circuits. It works on the basis of the principle of electromagnetic induction. Its main use is to increase (step up) …
