We discuss the alternative conceptions of students analysing the behaviour of electrical circuits. The present paper aims at, on one hand, studying the misconceptions of 80 elementary preservice teachers from Quebec in Canada, in relation to the current source in DC circuits. To do this, they completed a twochoice questionnaire (true or false) with justification. Data analysis identifies many conceptual difficulties. For example, their majority considered a battery as a source of constant current When a circuit composed of battery and resistors is modified, the current supplied by the battery remains unchanged. On the other hand, considering the alternatives conceptions identified we develop a twotier test about source current. The aim of this twotier test is to help teachers to diagnose rapidly their students’ misconceptions in order to consider in their teaching.
