Electrons.
The supporting metals are insulated from the current path and current cannot flow.
Conventionally electric current was assumed to be a flow of positive charges. But in reality especially in metals electric current is due to the flow of negatively charged electrons. So direction of conventional current is opposite to the direction of flow of electrons. But in case of liquids as well as solids electric current is due the flow of both positive and negative ions.
The flow of electric charges is current.
conclusion of electric current
It is called an electric current.
Yes, an electric current is the flow of charged particles.
DC current
potential difference make the current to flow. i think this can be compared with mechanical system as fluid flow as a result prssure difference between two points
A current.
welding
In metal conductors, electric current is the flow of electrons.
An electric current can be carried through a metal by the free flow of the shared electrons.
