Glass, porcelain, plastic and rubber are examples of non-conductive materials. These materials are also known as insulators. They are used to stop the flow of electricity. Insulators either prevent or block the flow of electrons. The atoms inside insulators do not have extra electrons that can move freely through a material.
This is a list of 10 examples of materials that are electrical conductors and insulators and a look at why some materials conduct better than others.
Non-conductors of electricity are also known as insulators. Insulators do not allow a significant amount of electrical current to flow through. Some examples of insulators are glass, rubber and plastic.
Ohmic conductors are conductors which obey ohms law. A good example of an Ohmic conductor is the resistor. The voltage drop across a resistor is directly correlated to the current that is flowing through it Non-Ohmic conductors do not follow Ohms ...
The answer is that some non-metals can conduct electricity.Carbon for example can conduct electricity. The real question is what is the difference between conductors and insulators.
CONDUCTORS AND INSULATORS. After reading this section you will be able to do the following: Contrast the characteristics of conductors and insulators. List examples of common conductors and insulators. Explain how insulators provide protection from electricity. In the previous pages, we have talked a bit about conductors and insulators .
This is because the resistance of some conductors changes as their temperature changes. These types of conductors are called non-ohmic conductors, because they do not obey Ohm’s Law. A light bulb is a common example of a non-ohmic conductor. Other examples of non-ohmic conductors are diodes and transistors.
Materials that lack electron conduction are insulators if they lack other mobile charges as well. For example, if a liquid or gas contains ions, then the ions can be made to flow as an electric current, and the material is a conductor. Electrolytes and plasmas contain ions and act as conductors whether or not electron flow is involved. Breakdown

Examples of Conductors and Insulators. Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air. The division of materials into the categories of conductors and insulators is a ...
