Question

The conduction of current by a conductor is either due to flow of ______ or due to the movement of ______.

Answer 1

The conduction of current by a conductor is either due to flow of electrons or due to the movement of ions.

Explanation:

Conduction of current occurs by electrons in metallic conductors and by ions in electrolytic conductors. In metals, free electrons move under an electric field, while in solutions, positive and negative ions carry current by migrating towards respective electrodes.
