Which description of current in a metal is correct

An electrical current in a metal wire is a flow of:ohmselectronsvoltsatoms

In a copper wire, the flow of current is made up of which of the following?A ionsB electronsC protonsD neutrons

Which of the following statement/s is/are correct about electric current:Statement 1 : It is the rate of flow of electrons.Statement 2 : It is the rate of flow of protons.

A flow of positive charges gives the same electric current, and has the same effect in a circuit, as an equal flow of negative charges in the opposite direction. Since current can be the flow of either positive or negative charges, or both, a convention is needed for the direction of current that is independent of the type of charge carriers. Negatively charged carriers, such as the electrons (the charge carriers in metal wires and many other electronic circuit components), therefore flow in the opposite direction of conventional current flow in an electrical circuit.[16][17]
