# How to read electrical circuits?

In order to learn how to read electricschema, you need, first of all, to know the symbols - that is, those symbols that occur in almost any scheme. It is about these symbols that we first of all talk. Next, we will consider what else, in addition to knowing these signs, is necessary for a person to become an expert in electrical engineering, and specifically, understanding how to apply knowledge of reading electrical circuits in practice.

## How to Read Electrical Circuits - Notation

Here I will give you the basic notation that can be found on almost any electrical circuit.

- The lines on the electrical circuit always indicate the wires.
- The dots denote the connection points.
- If you meet a small rectangle - it's a resistor.
- A circle with a cross inside denotes an LED or a light bulb. But the circle with the circle inside in the overwhelming majority of cases denotes an electric motor.
- If you meet an open line with an end pointed to the side, this is the place where the key is indicated.
- And, finally, the U-shaped rectangle will mean that there is a relay in this place.

Now take a look at any electrical circuit -surely you look at it already with different eyes. I recommend that you write down the above designations with explanations in the form of a table, so that, in case of what, they would be easy to find and explain. Well, and now some more tips, without which one can not do with someone who wants to learn how to read electrical circuits, because in addition to the knowledge of symbols, you need something else.

## How to learn to read electrical circuits

Of course, not everything is so simple. There are many special schemes where, even knowing all the notation, in order to properly understand them, you need to know the principle of the operation of a device. Therefore, download some sensible textbook on electrical engineering and start slowly mastering the basics of this difficult but interesting profession.

It is easy to understand symbols, but the most important is to understandthe principle of operation of these schemes, otherwise they will remain for you a set of symbols - even if now understandable. In addition, the electrical diagram gives an idea only of the principle of operation of the device. It is not enough to know how to read the electrical circuits, because in fact, these elements can be located in different parts of the device, so you need to stock up with a lot of knowledge in the field of electrical, electronics and electrical engineering. Only then can you not only read the diagrams, but also be able to apply this knowledge in practice. However, there would be a desire, and experience will come, so I'm sure - with the right motivation, you will succeed.
