The correct answer is: A. A conductor allows current to flow much easier than an insulator does.
A conductor is a material that allows electricity to flow through it easily. An insulator is a material that does not allow electricity to flow through it easily. Conductors are made of materials that have many free electrons. Free electrons are electrons that are not attached to any atoms. When a voltage is applied to a conductor, the free electrons move through the conductor, creating an electric current. Insulators are made of materials that have very few free electrons. The few free electrons that are present in an insulator are not able to move easily, so an insulator does not allow electricity to flow through it.
Option B is incorrect because an insulator does not have an excessive number of free electrons. Option C is incorrect because a conductor allows current to flow much easier than an insulator does. Option D is incorrect because the difference between conductors and insulators does not depend on how they are used. Option E is incorrect because A is the correct answer.
