We will present and compare questions and data from literature and identify four possible misconceptions about open switches. Across many different populations with students from different countries, we find that 54 % of students incorrectly think that the voltage across an open switch is zero. While this number of incorrect answers is quite consistent across all studies, not much is known about the student misconceptions that cause it. Consequently, further research into these misconceptions is required to help teachers design suitable instruction.enConference PaperOther
