Which of the following gives the best description of the motion of electrons in a conductor?

A.

The electrons in conductors usually move in straight lines.

B.

The electrons in conductors are able to move about freely.

C.

The electrons in insulators are unable to move about freely.

D.

The electrons in conductors usually move in regular patterns.

The correct answer is B. The electrons in conductors are able to move about freely.

Explanation:

The conductive materials are those that have an atomic structure that favors that the electrical charges can be easily moved inside. That is, a conductive material is one that allows the transport of electric charge, presenting little resistance to the movement of electric charge or electrons when an electric field is applied.

The arrangement and freedom of movement of the electrons along the atomic structure is what favors the circulation of electricity through the conductor.

So, the correct answer is B. The electrons in conductors are able to move about freely.
