The work objective is carried out a study about the comprehension achieved byundergraduate engineering students concerning energy processes in simple DC circuits. The methodology used in the research consisted of a first "exploratory" stage of more qualitative characteristics, which allowed us to state working hypotheses. In a second stage, of a more quantitative nature, written questionnaires were developed and administered to the students in order to experimentally test the formulated hypotheses. The research shows, on one hand, that many students do not adequately interpret some energy exchanges on a macroscopic basis. On the other hand, it also shows that they do not link (or they incorrectly link) macroscopic and microscopic interpretations of the proc-esses that energy undergoes in the circuit. Possible reasons are suggested for the detected mistakes; among them, the shortage of bibliography on the subject, the use of non-scientific modes of reasoning, the poor differentiation between the transitory and stationary stages that the circuits undergo, or the lack of discrimination between macroscopic and microscopic analysis. El objetivo del trabajo es estudiar la comprensión alcanzada por estudiantes de carreras de ingeniería, sobre procesos que sufre la energía en circuitos simples de corriente continua. La metodología constó de una primera etapa “exploratoria” de características más cualitativas, que permitió enunciar hipótesis de trabajo. En una segunda etapa, de índole más cuantitativa, se elaboraron y administraron a los estudiantes cuestionarios escritos, a fin de contrastar experimentalmente las hipótesis formuladas. La investigación muestra, por una parte, que muchos alumnos no interpretan adecuadamente ciertos intercambios energéticos desde un punto de vista macroscópico. Por otra parte, también se advierte que no relacionan o relacionan incorrectamente interpretaciones macroscópicas y microscópicas de los procesos que sufre la energía en el circuito. Se sugieren posibles razones para las incomprensiones detectadas; entre ellas, la escasez de bibliografía sobre el tema, la utilización de modos de razonamiento no científicos, la no diferenciación entre las etapas transitoria y estacionaria por las que atraviesa el circuito, o bien la no discriminación entre análisis macroscópicos y microscópicos.
