Question

in the lab frame, is the current carried by ions or by electrons or by both?

Answer 1

Answer:the current is carried by electrons in lab frame

Explanation:An electric current is the rate of flow of electric charge past a point[1]:2[2]:622 or region.[2]:614 An electric current is said to exist when there is a net flow of electric charge through a region.[3]:832 In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte or both ions and electrons such as in an ionized gas.
