Answer:
Insulator
Step-by-step explanation:
A body that has relatively few free electrons and offers comparatively great resistance to the movement of free electrons is an INSULATOR.
An insulator is a body that offers resistance to free flow of electrons. Insulators do not allow the passage of electric current. Examples of Insulators are glass, plastic, rubber, dry wood, paper, etc. The opposite of an insulator is a conductor. A conductor is body that allows free flow of electrons. Conductors allow the passage of electric current. Metals are the most common example of conductors such as copper, aluminum, gold, and silver. Other examples of conductors include grahite and human body.
