Serial connection or parallel connection?

There are basically three ways of associating resistors, they are circuit with the series association, a circuit with the parallel association, and circuit with the mixed association, which is formed by the series and parallel circuit. These connections are fundamental in electricity, so through a wiring diagram, we show how to make a parallel connection and a series connection, in addition to explaining what is a series circuit, parallel circuit, and where they are most used, come on guys!

What electrical circuit?

We can define a circuit as a closed path, where the end and the beginning belong to the same point. The term electrical circuit can be defined in a simple way, as one or more closed paths where the electric current travels. But for this concept to be clearer it is necessary to understand other elements present in an electrical circuit and that is what we are going to explain now.

A basic electrical circuit, which is functional, consists of a voltage source, which can be an outlet, batteries, batteries or any other source where there is a difference in electrical potential.

Another basic element in an electrical circuit is the load, which will consume electrical energy and transform it into another type of energy, which will later be used, for example, a lamp, a resistor, a motor, electrical equipment, etc.

Finally, the electrical conductors (electrical cables), which are fundamental, as they are responsible for forming a path to conduct the electrons (electrical current) between the source that produces it and the charge that consumes it, returning to the source and starting a new Circle.

What is a serial link?

The series circuit, also known as series connection, is a circuit composed exclusively of electrical or electronic components connected in sequence, that is, they have only one point in common between them. Therefore, the electric current will be the same passing through the components, regardless of the quantity.

What is a parallel connection?

The parallel connection, which is also known as a parallel circuit, is a circuit composed only of electrical or electronic components connected in parallel, that is, they have two points in common, and the electric current is divided proportionally to the value of each component.

What is the best type of connection to make?

Agora que sabemos um pouco sobre cada circuito, qual a melhor ligação a fazer? Série ou paralelo? É importante lembrar que além dessas duas ligações existe uma terceira, que é a ligação ou circuito misto, também conhecido como circuito série paralelo. Como o próprio nome já sugere, é um circuito cuja a sua composição é feita por elementos que estejam interligados em série e em paralelo.

O circuito misto é o maior e mais complexo de todos eles, por ser composto de circuitos em série e circuitos em paralelo, cada circuito misto possui sua singularidade, por esse motivo só é possível analisar o comportamento da tensão e corrente elétrica por partes do circuito, fazendo a associação deles.

We have a classic example of a connection or series circuit, which is the blinker! In some flashing models, the meshes are connected in parallel and the small lamps connected in series form the meshes. Therefore, the greatest evidence that it is a series connection, is that when you burn or remove one of the lamps all that mesh (part) stops working, because the current flow is interrupted, with no alternative path for the electric current.

The definition of where serial, parallel, and mixed connections are used depends on many factors! For example, within electrical and electronic equipment and devices, there can be all types of connections, especially mixed. In residential, building, and industrial electrical installations, the parallel connection is used, because the voltage must be the same in all installation circuits, and unlike what happens in the serial connection of the blinker, when you need to change the light bulb. a parallel connection, there will be no power interruption for the other equipment.

We can conclude that there is no better connection than the other or that it is more efficient, it is relative! Each of the connections is adapted to the needs of each project or electrical scheme, such as whether it will be necessary to deliver the same voltage to all loads, whether it will be necessary to interrupt the flow of electrical current to the load or both actions must be performed together.

We ended this article here and we hope to have cleared all doubts about what is the best connection to make! If you still have any questions on this subject, leave them in the comments and we will answer them!
