What symbol is used to identify a transformer?

The symbol that is used to identify a transformer is represented by a rectangular coil. This symbol effectively portrays the inductive nature of the transformer. A transformer operates based on the principle of electromagnetic induction, which involves coils of wire—one for the primary winding and one for the secondary winding. The rectangular shape signifies the form of the coil, allowing users to quickly identify the component in schematic representations.

In electrical schematics, the use of a coil symbol helps technicians and engineers recognize the transformer’s role in the circuitry, such as stepping up or stepping down voltage levels. The design of the rectangular coil symbol distinctly indicates its function at a glance, which is crucial for effective communication within electrical designs and safety protocols.
