How to Read Schematics for Beginners

How to read schematics for beginners – when starting to learn electronics, beginners need to learn how to read schematic diagrams. Schematic diagrams show the components and electrical connections of a circuit in schematic or diagram format. A schematic diagram is also known as a circuit diagram, or just schematic.

Schematic Symbols

Before being able to read a schematic, it is necessary to learn and recognize the symbol for each component in a circuit. Each symbol in a schematic represents a physical electrical or electronic component.

In the circuit above, the schematic is shown on the left and has two symbols representing two components. The symbol on the very left represents a battery. On the right of the schematic is the symbol that represents a light bulb.

On the right of the above image is the physical implementation of the schematic on the left. Here the actual light bulb and battery can be seen.

Electrical Connections

Electrical connections between the bulb and battery are represented by lines in the schematic. These lines are wires in the actual circuit.

How to Read Schematics

The article on how to read circuit diagrams for beginners on the Starting Electronics website shows the very basics of how to read schematics. This article uses the same light bulb and battery circuit to explain the basics of circuit diagrams. It shows how to recognize when two wires are connected, or whether they are just crossing each other.

After reading this article, a series of tutorials follows to get the reader to recognize electronic components and their schematic symbols. Each electronic circuit can be built on breadboard. A good way to learn how to read electronics schematics is to follow the tutorials, look at the schematic diagrams and build the circuits.
