Glass is not a good conductor of electricity and is classified as an insulator not a conductor. An electrical insulator is any material that does not allow electrons and electric charge to flow freely. These materials ma... More »

The conducting abilities of water depends on the type of water or the purity of it. Pure water, that does not have any other elements in it is a better insulator of electricity than it is a conductor. The opposite holds ... More »

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. More »

Silicon is typically a very poor conductor of electricity and often considered an insulator. However, a process called doping introduces a small amount of other material into the crystal structure to convert silicon from... More »

Glass is a good electrical insulator because the electrons in the glass are tightly bound to the atoms and do not transfer easily, thus keeping electricity from moving through the glass. Conversely, good electrical condu... More » Home & Garden Home Maintenance Building Materials

Wood is classified as an insulator and does not readily conduct electricity, but when wet, wood does have the potential to conduct electricity. Insulators resist the flow of electricity, as stated by the Occupational Saf... More »

A conductor conducts electricity, and an insulator, or a dielectric, does not. A semiconductor falls between the two extremes and conducts less electricity than a conductor but more than an insulator. Siemens per meter (... More »
