What is general in transformers?

Transformers are electrical devices used to transfer energy from one circuit to another through electromagnetic induction. They consist of two coils or windings, known as primary and secondary, which are wound around a magnetic core. The primary winding is connected to the input voltage source, while the secondary winding is connected to the load. When the voltage is applied to the primary winding, it creates a magnetic field in the core, which induces a voltage in the secondary winding. The magnitude of the voltage induced in the secondary winding depends on the number of turns in the winding and the ratio of turns between the primary and secondary winding. Transformers are used in a variety of applications, including power transmission and distribution, voltage regulation, and electrical isolation. They also play an important role in electronic equipment, such as computers, TVs, and audio systems. Transformers are available in different types and sizes, ranging from small transformers with a few watts of power to large power transformers that can handle several megawatts of power.
