Undergraduate students often encounter great difficulties in understanding Ohm\u2019s law and electrical
\ncircuits. Considering the widespread students\u2019 beliefs and their common mistakes, as they come out
\nfrom the literature and our teaching experience, we think that a relevant source of these problems
\ncomes from the fact that electrical circuits are generally treated separately from the other topics
\nof electromagnetism, with poor reference to the circulation of the electric field. We present here a
\nway to deal with electrical circuits that could help students to overcome their difficulties. In our
\napproach, the electric field is the protagonist and the mathematical tool the students are asked to
\nuse is its circulation. In the light of the circulation of the electric field, the experimental
\nOhm\u2019s law is revisited, the concept of electromotive force is discussed and some suggestions to
\neliminate common misconceptions about the role of a battery in a circuit are presented.<\/p>\n","protected":false},"excerpt":{"rendered":"
