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.
Jun 21, 2024 · What is a transformer? 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 voltage.

- Transformers are employed for widely varying purposes. For example, a transformer is often used to reduce the voltage of conventional power circuit...
- The iron core of a transformer is laminated to reduce eddy currents. Eddy currents are the small currents that result from the changing magnetic fi...
A transformer is a device used in the power transmission of electric energy. The transmission current is AC. It is commonly used to increase or decrease the supply voltage without a change in the frequency of AC between circuits. The transformer works on the basic principles of electromagnetic induction and mutual induction. Transformer Types

- Transformers burn and explode when lightning strikes, and during overloading, corrosion, power surges, etc.
- 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.
Apr 5, 2024 · A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works on the principle of Faraday’s law of induction by converting electrical energy from one value to another.
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 moving parts. It is used to control the voltage levels between circuits.
Aug 5, 2023 · How does a transformer work? A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it.
