Can a physical device have multiple schematic symbols?

A physical device can indeed have multiple schematic symbols, which is why the answer is yes. This flexibility is often necessary due to various engineering disciplines, design needs, or standards that may apply to the device in different contexts.

For example, a resistor may be represented differently based on whether it is a fixed resistor, a variable resistor, or in a particular circuit configuration. Furthermore, different industries or geographical regions may follow different conventions for representing the same component. Therefore, it’s not unusual for the same physical device to be depicted using different symbols in various schematic diagrams. This adaptability facilitates easier communication between engineers, technicians, and designers, ensuring they can work with the device within the context of their specific requirements or project standards.
