each block. This chapter will review the basic symbols and conventions used in both types of
drawings.
Electronic Schematic Drawing Symbology
Of all the different types of electronic drawings, electronic schematics provide the most detail
and information about a circuit. Each electronic component in a given circuit will be depicted
and in most cases its rating or other applicable component information will be provided. This
type of drawing provides the level of information needed to troubleshoot electronic circuits.
Electronic schematics are the most difficult type of drawing to read, because they require a very
high level of knowledge as to how each of the electronic components affects, or is affected by,
an electrical current. This chapter reviews only the symbols commonly used in depicting the
many components in electronic systems. Once mastered, this knowledge should enable the
reader to obtain a functional understanding of most electronic prints and schematics.
Figure 1 and Figure 2 illustrate the most common electronic symbols used on electronic
schematics.
