This article tries to analyse what the students' principal learning difficulties on the concept of charge and electric field are. In this way, we have supposed certain parallels between learning difficulties in these concepts and the problems in their formation throughout history. We have carried out a short description of principal epistemological problems, and a design based on a questionnaire containing open questions and personal interviews of secondary and University students. The results obtained seem to indicate that the students have problems to interpret electrification phenomena, which are not easy to explain by a hydrostatic model of electric charge. Likewise, we have verified that few students significantly use the concept of electric field.
