2. What Is a Circuit Diagram?

Circuit diagram is the graphical notation of the electrical circuit. We can also call the circuit diagram as electrical schematic and electrical diagram so doesn’t be confused in both. But a question that has been confusing till now is how to draw a circuit diagram? It is very simple, just place the desired electrical symbol in place of electrical components.

So as we know that we can’t draw the actual component, it is a very hard and time taking process, so to overcome this problem we use the desired electronic symbol in place of components and this makes it easy to draw.

We use circuit diagrams to make circuits easily. Through this circuit diagram, you can also plan your circuit that how it works, what to replace, and many more.

Example of a Circuit Diagram:

We have a simple circuit diagram with a battery, resistance, and a LED. So you can see how simple it is to draw a circuit diagram.

3. How to Read a Circuit Diagram?

When we come to make an electrical wiring using a circuit diagram a question comes into our mind that how to read a circuit diagram?

Don’t worry it is a very easy process to understand a schematic diagram, simply you have learned about the electrical symbol.

What are Electrical Symbols?

Electrical symbols are the graphical representation of various electrical components and electrical devices.
