Why transformer named as transformer ?
1 Answer
The term "transformer" in electrical engineering refers to a specific type of device that is used to transfer electrical energy between two or more circuits through electromagnetic induction. The name "transformer" is derived from its fundamental principle of operation, which involves transforming voltage and current levels from one circuit to another.
In a transformer, there are typically two coils of wire, known as the primary winding and the secondary winding, wound around a common core. When an alternating current (AC) voltage is applied to the primary winding, it generates a changing magnetic field in the core. This changing magnetic field induces a voltage in the secondary winding, which can then be used to power another circuit or device.
The term "transformer" accurately reflects the primary function of the device, which is to "transform" or change the voltage and current characteristics of an electrical signal while maintaining the same frequency. This ability to efficiently change voltage levels is crucial in various applications, such as in power transmission and distribution, where transformers play a key role in stepping up or stepping down voltages to minimize energy losses during long-distance transmission.
In summary, the name "transformer" is used because the device's primary purpose is to transform or change electrical voltage and current levels through electromagnetic induction.
