What is and how to make an electrical circuit

1 What is an electrical circuit?

The first thing you should know to understand how to make an electrical circuit is that they are fundamental in our daily lives, since they feed a variety of devices and systems that we use daily. From lighting a lamp to loading our mobile phone, the electrical circuits are present everywhere.

An electrical circuit is a closed route that allows the current to flow from an energy source, such as a battery or a plug, towards a device or load and then returns to the source. The electric current is the flow of electrons along this route, and is essential for the operation of electronic devices.

If you want it easier, we invite you to think about the electrical circuit as a road system why electrons, which are electrically charged particles, can circulate and provide energy to the devices they use daily.

Now, let's see how it works. In an electrical circuit, you need a energy source, which is like the power plant that supplies electricity. For electrons to travel, they need drivers. These are like the roads of the circuit, and usually, they are made of conductive materials, such as copper.

But electricity does not move simply by movement; You need to do something useful. The burden In a circuit is what this useful task performs. Finally, the switches: Imagine it as a traffic light on that road. You can open or close the circuit. When the switch is closed, it allows electricity to flow, and when it is open, it stops it.

2 Necessary material to make an electrical circuit

Now that you know what an electrical circuit is, it was time to plan what type of circuit you want to create. To do this, you can visit our article about the types of electrical schemes and try to make a simple diagram to visualize the disposition of the components you need.

Are you lazy software? Don't worry! In our step by step we first propose you to create the model on a white sheet.

Of course, to build a basic electrical circuit, you will need some fundamental elements that we list below:

1. A cardboard leaf or base for the model.
2. Conductive wires.
3. A battery (it can be AA or AAA).
4. Small or LED bulbs.
5. A switch (you can use a simple switch).
6. Adhesive tape.
7. Clips to hold the wires.
8. Snacks and labels (optional to identify components).

3 Step by step to make an electrical circuit

Creating an electrical circuit may seem challenging at the beginning, but with patience and understanding of the basic principles, anyone can become an amateur circuit builder. Are you ready?

Step 1: Base preparation

Take the cardboard sheet and decide where you will place the circuit elements. You can draw a simple design on the sheet to plan.

Step 2: battery connection

Place the battery at one end of the model. This will be the energy source. Make sure it is correctly oriented, with the properly identified positive and negative pole.

Step 3: switch connection

Now place the switch on the circuit. Connect one end of the switch to the positive pole of the battery and the other end to a point in the circuit where you want to control the electricity flow.

Step 4: Light connection

Connect the [LED bulbs] (

Connects the LED bulbs to the circuit. A limb of each bulb connects to the switch, and the other limb connects to the negative battery pole.

Step 5: Wire connections

Use conductive wires to make connections. You can peel the ends of the wires to ensure good conductivity. Use clips or adhesive tape to fix the wires to the model.

Step 6: Ensuring connections

Make sure all connections are well made. The wires must be firmly connected to the components. If necessary, use adhesive tape to maintain connections in place.

Step 7: Tests and Settings

Close the switch and see if the lights light. If not, check the connections and make sure everything is connected correctly.

4 Bonus: Tips to make your most didactic electrical circuit

Creating an electrical circuit will not only provide you with practical knowledge, but will also encourage your curiosity about the functioning of electricity in everyday life. If you have already encouraged yourself to create your project, we leave you some tips to learn and have fun a little more:

• You can decorate the model with colors and drawings to make it more attractive.
• Use different colors to identify cables and facilitate connection.
• Understand the symbol and function of each component in the circuit.
• If it is a school or family project, it encourages the little ones to label the components to better understand how the circuit works.

And remember: Always turn off the energy source before making adjustments in the circuit!
