Circuit, from the Latin circuitus, is a term with multiple meanings. It can be used to name the path in a sharp curve or the terrain that is located within any perimeter.
Electric, on the other hand, is that belonging to or relating to electricity (the physical property manifested by the attraction or repulsion between the parts of matter or the form of energy based on said property).
An electrical circuit, therefore, is the interconnection of two or more components that contains a closed path. Said components can be resistors, sources, switches, capacitors, semiconductors or cables, for example. When the circuit includes electronic components, it is referred to as an electronic circuit.
Among the parts of an electrical circuit, we can distinguish the conductors (cables that join the elements to form the circuit), the components (devices that allow the charge to flow), the nodes (points of the circuit where two or more conductors concur) and the branches (set of the elements of a circuit between two consecutive nodes).
Electric circuits can be classified according to the type of signal (direct current or alternating current), the type of configuration (series, parallel or mixed), the type of regime (periodic current, transient or permanent current) or the type of components (circuit electrical or electronic circuit).
The graphical representation of the electrical circuit is known as an electronic diagram or electrical scheme. This representation shows the components of the circuit with uniform pictograms according to certain standards, together with the interconnections (without these corresponding to the physical locations).
The preparation of this scheme is essential for the construction of an electrical circuit, since it represents the first step to follow. The operation of the circuit depends on how well elaborated it is, so it is very important to review it more than once and test the theory before proceeding.
How to build a simple electrical circuit?
As mentioned in the previous paragraph, the first thing that is needed is to capture the design of the electrical circuit in a diagram, that is, in a graphic representation of its various components and their connections, using the appropriate symbology, according to the conventions.
Once the scheme has been designed and tested, it is necessary to gather the following materials:
* 1 wooden board of approximately 20cm x 20cm (a plastic or cardboard base can also be used);
* 1 electric bulb;
* 1 piece of cable of the extension that is considered necessary (if it is possible to have 2, each one of a different color, the better);
* 1 common battery (also called a battery);
* 1 switch current;
* 1 lamp holder;
* electrical tape;
According to abbreviationfinder, the steps for the construction of the electrical circuit are as follows:
1) Stick the battery, switch and lamp holder on the table;
2) Cut three pieces of cable, and strip their ends (if you have cables of two colors, use one for the 2 negatives and the other for the positive);
3) Join one of the pieces of cable to the negative pole of the battery and the other to the switch, taking care that the latter is in its off position;
4) From the other end of the switch, connect a wire of the same color as the previous one to the lamp holder;
5) Close the connection cycle by joining the lamp holder to the positive pole of the battery, using a cable of a different color from the previous one;
6)Place the bulb in the socket, making sure that it fits snugly, but without exerting too much pressure, to prevent it from breaking;
7) To check that everything works as expected, flip the switch, at which point the bulb should light up.
