What Is and What Isn't an Electric Current?

Keywords: Electric Current
Electric current is defined like a movement of electrical charge from a region to another region inside an electric circuit. The most common form of electric current is related to a transport of electrons, and in this case the direction of a current is formally accepted as being opposite to electrons flow movement. But, an electric current can be a transport of positive or negative ions in an electrolytic cell, too. These are well known concepts written in any introductory physics books. The present text tries to answer to a simple question: Do these concepts correspond to experimental reality?
