These symbols are standardized, and various organizations, such as the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE), provide guidelines for their use. It's essential to understand these symbols when reading or creating circuit diagrams to design and troubleshoot electronic circuits. The following is a selection of some of the most common symbols. |

A reference designator is a component label on a schematic diagram to identify and differentiate between components. It usually consists of a letter indicating the type of component (e.g., "R" for resistor, "C" for capacitor, "D" for diode) followed by a unique number, such as "R1," "C2," or "D3". |
