It simply recognizes the symbols and observes how they connect to read schematics. A character is typically used to represent a component except for the ground and VCC symbols, which indicate a power supply connection. The lines connecting the symbols are wires that connect the parts. Reading schematics is an extremely useful skill to have. To begin developing your schematic reading skills, memorize the most common symbols. The ability to read and follow schematics is essential for any electronics engineer. The most basic circuit components and symbols! On a schematic, resistors are typically represented by a few zig-zag lines with two terminals extending outward. In international symbol schematics, a featureless rectangle may be used instead.
