Appendix A. Schematic Symbols
This section contains a compilation of schematic symbols for components that have been described in this volume. They are sequenced primarily in alphabetical order, as this section is intended for use as an index. However, symbols that have a strong similarity are grouped together; thus potentiometer is found adjacent to resistor, and all types of transistors are in the same group.
The symbol variants shown in each blue rectangle are functionally identical.
Where a component has mandatory polarity or is commonly used with a certain polarity, a red plus sign (+) has been added for guidance. This sign is not part of the symbol. In the case of polarized capacitors, where a plus sign is normally shown (or should be shown) ...
