What symbol typically denotes a transformer in TPC schematics?

In TPC schematics, the symbol for a transformer is represented by a rectangle featuring two coils. This design effectively illustrates the components of a transformer: the coils, which shall correspond to the primary and secondary windings, are necessary for the device's operation in transferring electrical energy between circuits through electromagnetic induction.

Using a rectangle to symbolize the transformer helps distinguish it from other components in the schematic, providing clarity when reading or interpreting the circuit. The two coils within this rectangle indicate how the transformer operates with inductance, supporting its role in voltage alteration (either stepping up or stepping down) as required in various electrical applications. This visual representation aligns with the standard conventions used in electrical engineering, making it easily recognizable to those familiar with circuit diagrams.
