Is the transformer an electric machine?

A transformer is an electric device, not a machine. It operates on the principle of electromagnetic induction to transfer electrical energy between two or more circuits through inductively coupled conductors. The primary components of a transformer are its coils or windings and a core, which is made of ferromagnetic material.

A transformer is classified as an electrical device, not an electronic one. Electrical devices convert electrical energy from one form to another, while electronic devices involve the flow of electrons through semiconductors, resistors, inductors, and capacitors to perform specific functions. Transformers do not involve complex electronic circuitry and are purely based on electromagnetic principles.

A transformer is considered a device rather than a machine because it has no moving parts. It functions by altering voltage levels through the interaction of its magnetic fields and windings, without any mechanical motion. Machines typically have moving parts and perform work through mechanical action, which is not the case for transformers.

A transformer is electrical, not mechanical. It deals with electrical energy and operates based on the principles of electricity and magnetism. There are no mechanical components or movements involved in its operation, distinguishing it from mechanical devices or machines.

An electrical machine is a device that converts mechanical energy to electrical energy or vice versa. Examples include motors and generators. Unlike transformers, electrical machines involve both electrical and mechanical processes, where components move to generate or use electrical power.
