Question

In the lab frame, the current is carried by electron r ions r by both?

Answer 1

Explanation:

The current in the wire, I say, is carried by the electrons which move with a (small!) velocity relative to the positive ions; we can suppose that the positive ...

Answer 2

$\Huge{\pink{\underline{\mathrm{ANSWER}}}}$

★ The current is carried by electrons in lab frame .

Explanation:

An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. 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.
