How to read diagrams?

An electronic circuit is a combination of certain electronic components, such as resistors, transistors, diodes, and other electrical components interconnected due to special microboards and contact tracks. Many engineers, technologists (and not only) meet with similar electrical circuits, and it is not always possible to correctly read and apply them in life. The article will talk about how to read the diagrams.

Reading schema

Any reading of an electrical circuit should begin with an introduction, i.e. reading the list of various elements, as well as notes and explanations to this or that condition.

Then, in a more detailed examination, the type of power supply, the type of various electrical devices (relays, motors, regulators, etc.) are determined.

After determining the devices, it is studied which specific scheme of the series is used by the engine, relay, regulator or other electrical device.

The main purpose of studying the electrical network are:

  • a clear definition of the conditions of action of the scheme;
  • detection of obvious errors, for example, the sequence of connecting components that can never be closed simultaneously;
  • correct identification of the cause of failures.

To learn how to read electrical circuits, it is necessary to responsibly and competently approach the above points.
