What are the three basic parts of a transformer?

A transformer consists of three essential components: windings, core, and enclosure.

The windings, which are typically made of copper or aluminum wire, are responsible for conducting electrical current. There are two sets of windings in a transformer: the primary winding, which receives input voltage, and the secondary winding, which delivers the transformed voltage output.

The core is made of ferromagnetic material and serves to channel the magnetic field generated by the alternating current in the windings. This magnetic field is crucial for the operation of the transformer, as it facilitates the transfer of energy between the primary and secondary windings through electromagnetic induction.

The enclosure provides physical protection for the internal components and helps in containing the magnetic field to improve efficiency and safety. While it is important for the overall structure and safeguarding of the transformer, it is the windings and core that are fundamental to its electrical function.

In summary, the combination of windings and core forms the operational heart of the transformer, enabling it to convert electrical energy from one voltage level to another efficiently.
