Answer:
a. the free movement of electrons within a conductor permits the transfer of change
Explanation:
Most conductors have more electrons than protons as well. And when you move from one conductor to another, the net charge on the conductor changes by the addition or subtraction of electrons only. In other words, all metals are charged and are considered to have a “positive charge.” A conductor permits energy, such as electric charge or heat, to flow freely through it.
