How is an inductor represented in TPC schematics?

In TPC schematics, an inductor is represented by a coiled line symbol. This representation effectively conveys the fundamental design and function of an inductor, which primarily consists of a wire wound into a coil that stores energy in a magnetic field when electrical current flows through it. The coiled line visually suggests the physical shape of inductors, making it easier for those interpreting the schematic to identify components and understand their roles in a circuit.

The other representations mentioned in the options do not represent inductors. For instance, a straight line with a square at the end typically symbolizes a resistor. A circular loop with a dot is often used to represent a junction or connection point rather than an inductor. Finally, two parallel lines are standard for depicting a capacitor. Each symbol serves a specific purpose, and recognizing the correct representation ensures clarity and accuracy in schematic diagrams.
