Question

In solid conductors ______ (ions/ electric charges) carry current through the material.

Answer 1

1. In solid conductors, the atoms are tightly closed to each other and some of the electrons are pragmatically free to move across the conductor, hence the current is carried by the negatively charged electrons.
2. But in an electrolytic solution, the current is carried by ions.

Hence, In solid conductors, electric charges carry current through the material.
