A circuit is a route or path that begins and ends in the same place, the starting point and the arrival point being the same. This path is established through different and numerous connections that can have different route options, although they always lead to the beginning of where they started. The circuit always happens or takes place in a defined space since it is closed and not infinite. This means that every circuit is arranged within a perimeter that, although it can vary in size greatly, is always delimited.
When it comes to circuits, the term can be applied to endless situations, even though some are better known than others. In this sense, common circuits are the electrical circuits that, properly connected to their elements, allow obtaining electricity in all the supports that need it. In addition, the circuits that occur inside machines and that have to do with technology, for example, the operating circuit of a computer, are complex circuits but also very common and important for the whole machine to function properly.
The word circuit can also be used in other types of spaces that have nothing to do with technology. Transport circuits are the routes already established to transport and mobilize materials, which have a starting point and an arrival point. At the same time, a very recurring circuit is that of auto racing. This circuit is established in a delimited perimeter (although it varies in size according to the disciplines) and it is the path that the different participants must complete, starting from a point and having to reach it to consider the complete lap. This circuit can have different branches of the route but it always has the same starting and finishing point.
