When there is an electric current passing through a wire, the particles moving are:

A. ions
B. atoms
C. protons
D. electrons



Answer :

Final answer:

Electric current is the flow of charged particles in a conductor, with electrons being the particles moving.


Explanation:

Electric current is the flow of charged particles in a conductor. In a wire, when there is an electric current passing through, the particles moving are electrons, which are negatively charged.

For example, in metal wires, current is carried by electrons, while in ionic solutions, both positive and negative charges move. This movement of charged particles constitutes the electric current.
