A little curiosity here. In my Electricity and Magnetism class, for the first half of the semester we were taught strictly: there can never be an electric field in a conductor. Alright, it makes sense the way it is explained, fair enough. Now we come to circuits, and are told that there is an electric field in the conducting wires that creates current, generated by the electromotive force. My question is, why is there an electric field in these wires? I thought it wasn't possible?
