Didactic Problems in the Concept of Electric Potential Difference and an Analysis of Its Philogenesis.

This paper makes an analysis of the different didactic problems to come from the fact that electric charge is inseparable from the mass, the impossibility of its direct observation (only its effects) and the meaning associated with the basic concepts of electricity, like electric potential or electric potential difference.In order to know the origin of the different meaning found in textbooks of the concept of electric potential difference, we have made an analysis of the relevant historical milestones. In this review, it is seen that the content assigned to it is taken from the mathematical formalism of field theory, which causes problems in its structure and its logico-formal communication as well as teaching problems.
