CIRCUIT DRAWINGS

In this section, we’ll examine and compare several different types of circuits.  In order to do this, you’ll need to examine a number of schematic diagrams. Schematic diagrams (or simply, “schematics”) are simplified drawings of electrical circuits that show all the electrical components of a circuit including the power source, conductors, loads, switches, resistors, and so on.

In your study of electricity and in actual electrical work, schematic diagrams are very  important. All electrical or electronic components are identified on schematic diagrams by standard symbols. You should try to memorize these symbols so that you can recognize them whenever you see them.
