Which symbol would typically represent an electrical transformer in a schematic?

The symbol that represents an electrical transformer in a schematic is commonly depicted as two circles. This design effectively illustrates the concept of magnetic coupling, which is fundamental to how transformers operate. In the case of a transformer, two coils are wound around a core, and the circles in the schematic symbolize these two windings. The configuration also implies the relationship and interaction between the primary and secondary windings, indicating how voltage can be transformed from one level to another through electromagnetic induction.

Using two circles allows for a clear and straightforward representation that conveys the essential function of a transformer without ambiguity. It aligns with standard practices in electrical engineering, where such symbols are universally recognized and understood by professionals in the field. This consistency is crucial for effective communication in diagrams and schematics.
