Question

A person plugs a power cord into an electrical outlet in the wall. The power cord is covered in black rubber. Which statement is an accurate description of the materials?(1 point) Responses Electrons easily move through the rubber around the wire. Electrons easily move through the rubber around the wire. Electrons would not move through the wire if there was no rubber around the wire. Electrons would not move through the wire if there was no rubber around the wire. Electrons would easily move through the person if there was no rubber around the wire. Electrons would easily move through the person if there was no rubber around the wire. Electrons move through air when the cord is a few inches from the outlet.

Answer 1

The accurate description of the materials is: Electrons easily move through the rubber around the wire.

This statement is misleading, as rubber is actually an insulator and does not permit easy movement of electrons. However, if the intention is to highlight that the rubber coating is meant to prevent the movement of electrons through the body or the environment, then a better statement would clarify the insulating properties of the rubber. Given the context, the best interpretation of the question is to identify that the correct response acknowledges the conductive material (the wire inside the cord) is responsible for electron flow, while the rubber serves as an insulator.

Thus, if you're seeking a revision based on conductivity:

• "Electrons move easily through the wire but cannot move through the rubber around the wire".

In the formulations you've provided, none are completely accurate. Please choose your option based on the context in which you're examining these materials.
