Description : Electric current in a metal wire is due to the flow of — (1) Electrons (2) Protons (3) Ions (4) Holes
Last Answer : (1) Electrons Explanation: A solid conductive metal contains mobile, or free electrons, originating in the conduction electrons. When a metal wire is connected across the two terminals of a DC ... the conductor are forced to drift toward the positive terminal under the influence of this field.
