Schematic Diagram:

Schematic diagrams are the standard means through that we communicate information in electronics and electrical circuits. On schematic diagrams, the component elements are represented through graphic symbols, a few of that were presented previously in Module 1. Since graphic symbols are short, it is possible to have diagrams in a compact form. A symbols and related lines display how circuit components are linked and the relationship of those components along with one another.

As an instance, let us look at a schematic diagram of a two-transistor radio circuit display in Figure. This diagram, from left to right, displays the elements in the sequence they are used to convert radio waves into sound energy. Through using this diagram it is possible to trace the operation of the circuit from starting to end. Due to this important characteristic of schematic diagrams, they are hugely used in maintenance, construction, and servicing of all types of electronic circuits.
