Sumario:This work shows that the same real physical system can be reduced to a point or infinite system under certain particular conditions. For this, the electric field created by a uniformly charged finite thread is calculated and it is observed that the same real physical system can behave as a point charge or as the opposite, an infinite wire. The objective of this article is to show a practical example of infinite and punctual models in physics for their application in the teaching of pre-universitary physics.
