is that electric current occupies space?

Yes, electric current does occupy space. Electric current is the flow of electric charge through a conductor, such as a wire. When current flows through a wire, it is carried by moving electrons. Electrons are negatively charged particles that are part of the atoms in the conductor.

The movement of electrons occurs within the conductor and follows a specific path, typically from one end of the conductor to another. As the electrons flow, they occupy physical space within the conductor. However, it is important to note that the space occupied by the electrons themselves is very small compared to the overall size of the conductor.

So, while electric current itself does not have a physical presence, it is carried by moving electrons that do occupy space within the conductor through which the current flows.
