The symbol that represents a tapped inductor in schematic diagrams is indeed symbol 7. A tapped inductor is an inductor with a connection at an intermediate point, allowing for the extraction of a portion of the inductive reactance. In circuit designs and schematics, distinct symbols are used to convey different components and configurations.

Symbol 7 specifically conveys this characteristic of a tapped inductor, illustrating how one end of the winding is connected to the tap point, making it visually clear to a technician or engineer that this inductor is not a simple coil, but has multiple output points for various circuit design applications. Tapped inductors are utilized for different purposes, such as providing variable inductance or in transformer-like applications where multiple voltages or signal levels may need to be accessed.

Understanding this symbol is crucial for anyone working with analog circuits, RF applications, or any areas where inductive components play a vital role in circuit functionality, as it enables correct interpretation and implementation of circuit designs that involve such components.
